requestProvisionalNotificationAuthorization method
Call this method to ask iOS for a provisional notification authorization. Batch will then automatically ask for a push token. This does not do anything on Android.
Provisional authorization will NOT show a popup asking for user authorization, but notifications will NOT be displayed on the lock screen, or as a banner when the phone is unlocked. They will directly be sent to the notification center, accessible when the user swipes up on the lockscreen, or down from the statusbar when unlocked.
This method does nothing on iOS 11 or lower.
Implementation
