Request notification permissions
To process push notifications successfully on Android 13 (API level 33) and later, the app must request the new Notification runtime permission for sending non-exempt notifications from an app.
To request the new notification permission from your app,
update your app to target Android 13 (API level 33) and declare
POST_NOTIFICATIONS in your app’s manifest file,
as in the following code snippet:
<manifest ...> <uses-permission android:name="android.permission.POST_NOTIFICATIONS"/> <application ...> ... </application> </manifest>
