check
Requests the runtime permissions a call needs, prompting the user when any are missing and reporting the outcome on permissionHandler. When all of them are already held it reports success without showing anything.
Do this before creating tracks or joining. Nothing else prompts: without the permission the track factories throw 3017 / 3018, and a room leaves that device off.
Permission.audio covers RECORD_AUDIO and MODIFY_AUDIO_SETTINGS, Permission.video covers CAMERA, and Permission.bluetooth covers BLUETOOTH_CONNECT on Android 12 and newer — below that it asks for nothing.
Parameters

told which permissions were granted, denied or blocked. PermissionHandler.onGranted runs inline on the calling thread when everything was already held; every other outcome arrives on the main thread.
