+#### Permissions
 - React Native SDK requests camera and microphone access, make sure to include the required entries for `NSCameraUsageDescription` and `NSMicrophoneUsageDescription`in your `Info.plist` file.
 - React Native SDK shows and hides the status bar based on the conference state,
   you may want to set `UIViewControllerBasedStatusBarAppearance` to `NO` in your
   `Info.plist` file.
 - For starting screen sharing React Native SDK provides the UI to present the `RPSystemBroadcastPickerView` to the user. By default, the picker will display a list of all the available broadcast providers. In order to limit the picker to our particular broadcast provider, we have to set `preferredExtension` to the bundle identifier of the broadcast extension. We are doing this by adding a new key named `RTCScreenSharingExtension` to the app's Info.plist and setting the broadcast extension bundle identifier as the value.
 - Make sure `voip` is added to `UIBackgroundModes`, in the app's `Info.plist`, in order to work when the app is in the background.
