checkAndroidPermissionsGroup
Return
A Pair where:
firstindicates whether all required permissions are granted (trueif granted,falseotherwise).secondcontains a Set of missing permissions (empty if all permissions are granted).
e.g. if the user granted the android.Manifest.permission.RECORD_AUDIO and the Call.state.ownCapability has "SendAudio" then we are safe to join and use the call since the permission for recording audio is granted and the user can stream the audio track.
