External authenticator apps may need to start background activities (for example, to allow users enter a pin code), but starting from Android 14, if the app bound to the service is targeting Android 14 or higher, it no longer allows the app that has the service to start a background activity by default. We need to add flag BIND_ALLOW_ACTIVITY_STARTS to allow the external authenticator app to start background activities.
