+
+A frameless window is a window that has no
+[chrome](https://developer.mozilla.org/en-US/docs/Glossary/Chrome), the parts of
+the window, like toolbars, that are not a part of the web page. These are
+options on the [`BrowserWindow`](browser-window.md) class.
+
+## Create a frameless window
+
+To create a frameless window, you need to set `frame` to `false` in
+[BrowserWindow](browser-window.md)'s `options`:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ width: 800, height: 600, frame: false })
+win.show()
+```
+
+### Alternatives on macOS
+
+There's an alternative way to specify a chromeless window.
+Instead of setting `frame` to `false` which disables both the titlebar and window controls,
+you may want to have the title bar hidden and your content extend to the full window size,
+yet still preserve the window controls ("traffic lights") for standard window actions.
+You can do so by specifying the `titleBarStyle` option:
+
+#### `hidden`
+
+Results in a hidden title bar and a full size content window, yet the title bar still has the standard window controls (“traffic lights”) in the top left.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'hidden' })
+win.show()
+```
+
+#### `hiddenInset`
+
+Results in a hidden title bar with an alternative look where the traffic light buttons are slightly more inset from the window edge.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'hiddenInset' })
+win.show()
+```
+
+#### `customButtonsOnHover`
+
+Uses custom drawn close, and miniaturize buttons that display
+when hovering in the top left of the window. The fullscreen button
+is not available due to restrictions of frameless windows as they
+interface with Apple's macOS window masks. These custom buttons prevent
+issues with mouse events that occur with the standard window toolbar buttons.
+This option is only applicable for frameless windows.
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ titleBarStyle: 'customButtonsOnHover', frame: false })
+win.show()
+```
+
+## Windows Control Overlay
+
+On macOS, when using a frameless window in conjuction with `win.setWindowButtonVisibility(true)` or using one of the `titleBarStyle`s described above so
+that the traffic lights are visible, you can access the Window Controls Overlay [JavaScript APIs][overlay-javascript-apis] and
+[CSS Environment Variables][overlay-css-env-vars] by setting the `titleBarOverlay` option to true:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({
+  titleBarStyle: 'hiddenInset',
+  titleBarOverlay: true
+})
+win.show()
+```

+window transparent:

+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow({ transparent: true, frame: false })
+win.show()
+```
+
+### Limitations
+
+* You can not click through the transparent area. We are going to introduce an
+  API to set window shape to solve this, see
+  [our issue](https://github.com/electron/electron/issues/1335) for details.
+* Transparent windows are not resizable. Setting `resizable` to `true` may make
+  a transparent window stop working on some platforms.
+* The `blur` filter only applies to the web page, so there is no way to apply
+  blur effect to the content below the window (i.e. other applications open on
+  the user's system).
+* The window will not be transparent when DevTools is opened.
+* On Windows operating systems,
+  * transparent windows will not work when DWM is
+  disabled.
+  * transparent windows can not be maximized using the Windows system menu or by double clicking the title bar. The reasoning behind this can be seen on [this pull request](https://github.com/electron/electron/pull/28207).
+* On Linux, users have to put `--enable-transparent-visuals --disable-gpu` in
+  the command line to disable GPU and allow ARGB to make transparent window,
+  this is caused by an upstream bug that [alpha channel doesn't work on some
+  NVidia drivers](https://bugs.chromium.org/p/chromium/issues/detail?id=369209) on
+  Linux.
+* On Mac, the native window shadow will not be shown on a transparent window.
+
+## Click-through window
+
+To create a click-through window, i.e. making the window ignore all mouse
+events, you can call the [win.setIgnoreMouseEvents(ignore)][ignore-mouse-events]
+API:
+
+```javascript
+const { BrowserWindow } = require('electron')
+const win = new BrowserWindow()
+win.setIgnoreMouseEvents(true)
+```
+
+### Forwarding
+
+Ignoring mouse messages makes the web page oblivious to mouse movement, meaning
+that mouse movement events will not be emitted. On Windows operating systems an
+optional parameter can be used to forward mouse move messages to the web page,
+allowing events such as `mouseleave` to be emitted:
+
+```javascript
+const { ipcRenderer } = require('electron')
+const el = document.getElementById('clickThroughElement')
+el.addEventListener('mouseenter', () => {
+  ipcRenderer.send('set-ignore-mouse-events', true, { forward: true })
+})
+el.addEventListener('mouseleave', () => {
+  ipcRenderer.send('set-ignore-mouse-events', false)
+})
+
+// Main process
+const { ipcMain } = require('electron')
+ipcMain.on('set-ignore-mouse-events', (event, ...args) => {
+  BrowserWindow.fromWebContents(event.sender).setIgnoreMouseEvents(...args)
+})
+```
+
+This makes the web page click-through when over `el`, and returns to normal
+outside it.
+
+## Draggable region
+
+By default, the frameless window is non-draggable. Apps need to specify
+`-webkit-app-region: drag` in CSS to tell Electron which regions are draggable
+(like the OS's standard titlebar), and apps can also use
+`-webkit-app-region: no-drag` to exclude the non-draggable area from the
+ draggable region. Note that only rectangular shapes are currently supported.
+
+Note: `-webkit-app-region: drag` is known to have problems while the developer tools are open. See this [GitHub issue](https://github.com/electron/electron/issues/3647) for more information including a workaround.
+
+To make the whole window draggable, you can add `-webkit-app-region: drag` as
+`body`'s style:
+
+```html
+<body style="-webkit-app-region: drag">
+</body>
+```
+
+And note that if you have made the whole window draggable, you must also mark
+buttons as non-draggable, otherwise it would be impossible for users to click on
+them:
+
+```css
+button {
+  -webkit-app-region: no-drag;
+}
+```
+
+If you're only setting a custom titlebar as draggable, you also need to make all
+buttons in titlebar non-draggable.
+
+## Text selection
+
+In a frameless window the dragging behavior may conflict with selecting text.
+For example, when you drag the titlebar you may accidentally select the text on
+the titlebar. To prevent this, you need to disable text selection within a
+draggable area like this:
+
+```css
+.titlebar {
+  -webkit-user-select: none;
+  -webkit-app-region: drag;
+}
+```
+
+## Context menu
+
+On some platforms, the draggable area will be treated as a non-client frame, so
+when you right click on it a system menu will pop up. To make the context menu
+behave correctly on all platforms you should never use a custom context menu on
+draggable areas.

 # Accessibility
 
+Making accessible applications is important and we're happy to provide
+functionality to [Devtron][devtron] and [Spectron][spectron] that gives
+developers the opportunity to make their apps better for everyone.
+

+
 Accessibility concerns in Electron applications are similar to those of
-websites because they're both ultimately HTML.
+websites because they're both ultimately HTML. With Electron apps, however,
+you can't use the online resources for accessibility audits because your app
+doesn't have a URL to point the auditor to.
+
+These features bring those auditing tools to your Electron app. You can
+choose to add audits to your tests with Spectron or use them within DevTools
+with Devtron. Read on for a summary of the tools.
+
+## Spectron
+
+In the testing framework Spectron, you can now audit each window and `<webview>`
+tag in your application. For example:
+
+```javascript
+app.client.auditAccessibility().then(function (audit) {
+  if (audit.failed) {
+    console.error(audit.message)
+  }
+})
+```
+
+You can read more about this feature in [Spectron's documentation][spectron-a11y].
+
+## Devtron
+
+In Devtron, there is an accessibility tab which will allow you to audit a
+page in your app, sort and filter the results.
+
+![devtron screenshot][devtron-screenshot]

+# Automated Testing with a Custom Driver
+
+To write automated tests for your Electron app, you will need a way to "drive" your application. [Spectron](https://electronjs.org/spectron) is a commonly-used solution which lets you emulate user actions via [WebDriver](https://webdriver.io/). However, it's also possible to write your own custom driver using node's builtin IPC-over-STDIO. The benefit of a custom driver is that it tends to require less overhead than Spectron, and lets you expose custom methods to your test suite.
+
+To create a custom driver, we'll use Node.js' [child_process](https://nodejs.org/api/child_process.html) API. The test suite will spawn the Electron process, then establish a simple messaging protocol:
+
+```js
+const childProcess = require('child_process')
+const electronPath = require('electron')
+
+// spawn the process
+const env = { /* ... */ }
+const stdio = ['inherit', 'inherit', 'inherit', 'ipc']
+const appProcess = childProcess.spawn(electronPath, ['./app'], { stdio, env })
+
+// listen for IPC messages from the app
+appProcess.on('message', (msg) => {
+  // ...
+})
+
+// send an IPC message to the app
+appProcess.send({ my: 'message' })
+```
+
+From within the Electron app, you can listen for messages and send replies using the Node.js [process](https://nodejs.org/api/process.html) API:
+
+```js
+// listen for IPC messages from the test suite
+process.on('message', (msg) => {
+  // ...
+})
+
+// send an IPC message to the test suite
+process.send({ my: 'message' })
+```
+
+We can now communicate from the test suite to the Electron app using the `appProcess` object.
+
+For convenience, you may want to wrap `appProcess` in a driver object that provides more high-level functions. Here is an example of how you can do this:
+
+```js
+class TestDriver {
+  constructor ({ path, args, env }) {
+    this.rpcCalls = []
+
+    // start child process
+    env.APP_TEST_DRIVER = 1 // let the app know it should listen for messages
+    this.process = childProcess.spawn(path, args, { stdio: ['inherit', 'inherit', 'inherit', 'ipc'], env })
+
+    // handle rpc responses
+    this.process.on('message', (message) => {
+      // pop the handler
+      const rpcCall = this.rpcCalls[message.msgId]
+      if (!rpcCall) return
+      this.rpcCalls[message.msgId] = null
+      // reject/resolve
+      if (message.reject) rpcCall.reject(message.reject)
+      else rpcCall.resolve(message.resolve)
+    })
+
+    // wait for ready
+    this.isReady = this.rpc('isReady').catch((err) => {
+      console.error('Application failed to start', err)
+      this.stop()
+      process.exit(1)
+    })
+  }
+
+  // simple RPC call
+  // to use: driver.rpc('method', 1, 2, 3).then(...)
+  async rpc (cmd, ...args) {
+    // send rpc request
+    const msgId = this.rpcCalls.length
+    this.process.send({ msgId, cmd, args })
+    return new Promise((resolve, reject) => this.rpcCalls.push({ resolve, reject }))
+  }
+
+  stop () {
+    this.process.kill()
+  }
+}
+```
+
+In the app, you'd need to write a simple handler for the RPC calls:
+
+```js
+if (process.env.APP_TEST_DRIVER) {
+  process.on('message', onMessage)
+}
+
+async function onMessage ({ msgId, cmd, args }) {
+  let method = METHODS[cmd]
+  if (!method) method = () => new Error('Invalid method: ' + cmd)
+  try {
+    const resolve = await method(...args)
+    process.send({ msgId, resolve })
+  } catch (err) {
+    const reject = {
+      message: err.message,
+      stack: err.stack,
+      name: err.name
+    }
+    process.send({ msgId, reject })
+  }
+}
+
+const METHODS = {
+  isReady () {
+    // do any setup needed
+    return true
+  }
+  // define your RPC-able methods here
+}
+```
+
+Then, in your test suite, you can use your test-driver as follows:
+
+```js
+const test = require('ava')
+const electronPath = require('electron')
+
+const app = new TestDriver({
+  path: electronPath,
+  args: ['./app'],
+  env: {
+    NODE_ENV: 'test'
+  }
+})
+test.before(async t => {
+  await app.isReady
+})
+test.after.always('cleanup', async t => {
+  await app.stop()
+})
+```

-# Automated Testing
-
-Test automation is an efficient way of validating that your application code works as intended.
-While Electron doesn't actively maintain its own testing solution, this guide will go over a couple
-ways you can run end-to-end automated tests on your Electron app.
-
-## Using the WebDriver interface
-
-From [ChromeDriver - WebDriver for Chrome][chrome-driver]:
-
-> WebDriver is an open source tool for automated testing of web apps across many
-> browsers. It provides capabilities for navigating to web pages, user input,
-> JavaScript execution, and more. ChromeDriver is a standalone server which
-> implements WebDriver's wire protocol for Chromium. It is being developed by
-> members of the Chromium and WebDriver teams.
-
-There are a few ways that you can set up testing using WebDriver.
-
-### With WebdriverIO
-
-[WebdriverIO](https://webdriver.io/) (WDIO) is a test automation framework that provides a
-Node.js package for testing with WebDriver. Its ecosystem also includes various plugins
-(e.g. reporter and services) that can help you put together your test setup.
-
-#### Install the testrunner
-
-First you need to run the WebdriverIO starter toolkit in your project root directory:
-
-```sh npm2yarn
-npx wdio . --yes
-```
-
-This installs all necessary packages for you and generates a `wdio.conf.js` configuration file.
-
-#### Connect WDIO to your Electron app
-
-Update the capabilities in your configuration file to point to your Electron app binary:
-
-```javascript title='wdio.conf.js'
-export.config = {
-  // ...
-  capabilities: [{
-    browserName: 'chrome',
-    'goog:chromeOptions': {
-      binary: '/path/to/your/electron/binary', // Path to your Electron binary.
-      args: [/* cli arguments */] // Optional, perhaps 'app=' + /path/to/your/app/
-    }
-  }]
-  // ...
-}
-```
-
-#### Run your tests
-
-To run your tests:
-
-```sh
-$ npx wdio run wdio.conf.js
-```
-
-[chrome-driver]: https://sites.google.com/chromium.org/driver/
-
-### With Selenium
-
-[Selenium](https://www.selenium.dev/) is a web automation framework that
-exposes bindings to WebDriver APIs in many languages. Their Node.js bindings
-are available under the `selenium-webdriver` package on NPM.
-
-#### Run a ChromeDriver server
-
-In order to use Selenium with Electron, you need to download the `electron-chromedriver`
-binary, and run it:
-
-```sh npm2yarn
-npm install --save-dev electron-chromedriver
-./node_modules/.bin/chromedriver
-Starting ChromeDriver (v2.10.291558) on port 9515
-Only local connections are allowed.
-```
-
-Remember the port number `9515`, which will be used later.
-
-#### Connect Selenium to ChromeDriver
-
-Next, install Selenium into your project:
-
-```sh npm2yarn
-npm install --save-dev selenium-webdriver
-```
-
-Usage of `selenium-webdriver` with Electron is the same as with
-normal websites, except that you have to manually specify how to connect
-ChromeDriver and where to find the binary of your Electron app:
-
-```js title='test.js'
-const webdriver = require('selenium-webdriver')
-const driver = new webdriver.Builder()
-  // The "9515" is the port opened by ChromeDriver.
-  .usingServer('http://localhost:9515')
-  .withCapabilities({
-    'goog:chromeOptions': {
-      // Here is the path to your Electron binary.
-      binary: '/Path-to-Your-App.app/Contents/MacOS/Electron'
-    }
-  })
-  .forBrowser('chrome') // note: use .forBrowser('electron') for selenium-webdriver <= 3.6.0
-  .build()
-driver.get('http://www.google.com')
-driver.findElement(webdriver.By.name('q')).sendKeys('webdriver')
-driver.findElement(webdriver.By.name('btnG')).click()
-driver.wait(() => {
-  return driver.getTitle().then((title) => {
-    return title === 'webdriver - Google Search'
-  })
-}, 1000)
-driver.quit()
-```
-
-## Using a custom test driver
-
-It's also possible to write your own custom driver using Node.js' built-in IPC-over-STDIO.
-Custom test drivers require you to write additional app code, but have lower overhead and let you
-expose custom methods to your test suite.
-
-To create a custom driver, we'll use Node.js' [`child_process`](https://nodejs.org/api/child_process.html) API.
-The test suite will spawn the Electron process, then establish a simple messaging protocol:
-
-```js title='testDriver.js'
-const childProcess = require('child_process')
-const electronPath = require('electron')
-
-// spawn the process
-const env = { /* ... */ }
-const stdio = ['inherit', 'inherit', 'inherit', 'ipc']
-const appProcess = childProcess.spawn(electronPath, ['./app'], { stdio, env })
-
-// listen for IPC messages from the app
-appProcess.on('message', (msg) => {
-  // ...
-})
-
-// send an IPC message to the app
-appProcess.send({ my: 'message' })
-```
-
-From within the Electron app, you can listen for messages and send replies using the Node.js
-[`process`](https://nodejs.org/api/process.html) API:
-
-```js title='main.js'
-// listen for messages from the test suite
-process.on('message', (msg) => {
-  // ...
-})
-
-// send a message to the test suite
-process.send({ my: 'message' })
-```
-
-We can now communicate from the test suite to the Electron app using the `appProcess` object.
-
-For convenience, you may want to wrap `appProcess` in a driver object that provides more
-high-level functions. Here is an example of how you can do this. Let's start by creating
-a `TestDriver` class:
-
-```js title='testDriver.js'
-class TestDriver {
-  constructor ({ path, args, env }) {
-    this.rpcCalls = []
-
-    // start child process
-    env.APP_TEST_DRIVER = 1 // let the app know it should listen for messages
-    this.process = childProcess.spawn(path, args, { stdio: ['inherit', 'inherit', 'inherit', 'ipc'], env })
-
-    // handle rpc responses
-    this.process.on('message', (message) => {
-      // pop the handler
-      const rpcCall = this.rpcCalls[message.msgId]
-      if (!rpcCall) return
-      this.rpcCalls[message.msgId] = null
-      // reject/resolve
-      if (message.reject) rpcCall.reject(message.reject)
-      else rpcCall.resolve(message.resolve)
-    })
-
-    // wait for ready
-    this.isReady = this.rpc('isReady').catch((err) => {
-      console.error('Application failed to start', err)
-      this.stop()
-      process.exit(1)
-    })
-  }
-
-  // simple RPC call
-  // to use: driver.rpc('method', 1, 2, 3).then(...)
-  async rpc (cmd, ...args) {
-    // send rpc request
-    const msgId = this.rpcCalls.length
-    this.process.send({ msgId, cmd, args })
-    return new Promise((resolve, reject) => this.rpcCalls.push({ resolve, reject }))
-  }
-
-  stop () {
-    this.process.kill()
-  }
-}
-
-module.exports = { TestDriver };
-```
-
-In your app code, can then write a simple handler to receive RPC calls:
-
-```js title='main.js'
-const METHODS = {
-  isReady () {
-    // do any setup needed
-    return true
-  }
-  // define your RPC-able methods here
-}
-
-const onMessage = async ({ msgId, cmd, args }) => {
-  let method = METHODS[cmd]
-  if (!method) method = () => new Error('Invalid method: ' + cmd)
-  try {
-    const resolve = await method(...args)
-    process.send({ msgId, resolve })
-  } catch (err) {
-    const reject = {
-      message: err.message,
-      stack: err.stack,
-      name: err.name
-    }
-    process.send({ msgId, reject })
-  }
-}
-
-if (process.env.APP_TEST_DRIVER) {
-  process.on('message', onMessage)
-}
-```
-
-Then, in your test suite, you can use your `TestDriver` class with the test automation
-framework of your choosing. The following example uses
-[`ava`](https://www.npmjs.com/package/ava), but other popular choices like Jest
-or Mocha would work as well:
-
-```js title='test.js'
-const test = require('ava')
-const electronPath = require('electron')
-const { TestDriver } = require('./testDriver')
-
-const app = new TestDriver({
-  path: electronPath,
-  args: ['./app'],
-  env: {
-    NODE_ENV: 'test'
-  }
-})
-test.before(async t => {
-  await app.isReady
-})
-test.after.always('cleanup', async t => {
-  await app.stop()
-})
-```

 Context Isolation is a feature that ensures that both your `preload` scripts and Electron's internal logic run in a separate context to the website you load in a [`webContents`](../api/web-contents.md).  This is important for security purposes as it helps prevent the website from accessing Electron internals or the powerful APIs your preload script has access to.
 
-This means that the `window` object that your preload script has access to is actually a **different** object than the website would have access to.  For example, if you set `window.hello = 'wave'` in your preload script and context isolation is enabled, `window.hello` will be undefined if the website tries to access it.

-Exposing APIs from your preload script to a loaded website in the renderer process is a common use-case. With context isolation disabled, your preload script would share a common global `window` object with the renderer. You could then attach arbitrary properties to a preload script:

-If you're building your Electron app with TypeScript, you'll want to add types to your APIs exposed over the context bridge. The renderer's `window` object won't have the correct typings unless you extend the types with a [declaration file].
-
-For example, given this `preload.ts` script:
-
-```typescript title='preload.ts'
-contextBridge.exposeInMainWorld('electronAPI', {
-  loadPreferences: () => ipcRenderer.invoke('load-prefs')
-})
-```
-
-You can create a `renderer.d.ts` declaration file and globally augment the `Window` interface:
-
-```typescript title='renderer.d.ts'
-export interface IElectronAPI {
-  loadPreferences: () => Promise<void>,
-}
-
-declare global {
-  interface Window {
-    electronAPI: IElectronAPI
-  }
-}
-```
-
-Doing so will ensure that the TypeScript compiler will know about the `electronAPI` property on your global `window` object when writing scripts in your renderer process:
-
-```typescript title='renderer.ts'
-window.electronAPI.loadPreferences()
-```

-difference between Electron and browsers is what happens when device access is
-requested.  In a browser, users are presented with a popup where they can grant

-  and [`hid-device-removed`](../api/session.md#event-hid-device-removed) events
-  on the Session can be used to handle devices being plugged in or unplugged during the
-  `navigator.hid.requestDevice` process.
-* [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
-  can be used to provide default permissioning to devices without first calling
-  for permission to devices via `navigator.hid.requestDevice`.  Additionally,
-  the default behavior of Electron is to store granted device permision through
-  the lifetime of the corresponding WebContents.  If longer term storage is
-  needed, a developer can store granted device permissions (eg when handling
-  the `select-hid-device` event) and then read from that storage with
-  `setDevicePermissionHandler`.
-* [`ses.setPermissionCheckHandler(handler)`](../api/session.md#sessetpermissioncheckhandlerhandler)
-  can be used to disable HID access for specific origins.
-
-### Blocklist
-
-By default Electron employs the same [blocklist](https://github.com/WICG/webhid/blob/main/blocklist.txt)
-used by Chromium.  If you wish to override this behavior, you can do so by
-setting the `disable-hid-blocklist` flag:
-
-```javascript
-app.commandLine.appendSwitch('disable-hid-blocklist')
-```
-
-### Example
-
-This example demonstrates an Electron application that automatically selects
-HID devices through [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
-and through [`select-hid-device` event on the Session](../api/session.md#event-select-hid-device)
-when the `Test WebHID` button is clicked.
-
-```javascript fiddle='docs/fiddles/features/web-hid'

-
-## Web Serial API
-
-The [Web Serial API](https://web.dev/serial/) can be used to access serial
-devices that are connected via serial port, USB, or Bluetooth.  In order to use
-this API in Electron, developers will need to handle the
-[`select-serial-port` event on the Session](../api/session.md#event-select-serial-port)
-associated with the serial port request.
-
-There are several additional APIs for working with the Web Serial API:
-
-* The [`serial-port-added`](../api/session.md#event-serial-port-added)
-  and [`serial-port-removed`](../api/session.md#event-serial-port-removed) events
-  on the Session can be used to handle devices being plugged in or unplugged during the
-  `navigator.serial.requestPort` process.
-* [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
-  can be used to provide default permissioning to devices without first calling
-  for permission to devices via `navigator.serial.requestPort`.  Additionally,
-  the default behavior of Electron is to store granted device permision through
-  the lifetime of the corresponding WebContents.  If longer term storage is
-  needed, a developer can store granted device permissions (eg when handling
-  the `select-serial-port` event) and then read from that storage with
-  `setDevicePermissionHandler`.
-* [`ses.setPermissionCheckHandler(handler)`](../api/session.md#sessetpermissioncheckhandlerhandler)
-  can be used to disable serial access for specific origins.

-### Example
-
-This example demonstrates an Electron application that automatically selects
-serial devices through [`ses.setDevicePermissionHandler(handler)`](../api/session.md#sessetdevicepermissionhandlerhandler)
