You can simply disable notifications in Android app settings, but an Exposed module is more sexy, of course
My app registers the rSA profile after it is started. The first thing the car does, is to query the profile list. So when my app is not immediately
started, the car will not know that the phone supports rSAP. So I guess it's not very reliable.
A service with an active notification must not be stopped by Android, so I guess there is something else going wrong. Maybe the Exposed module not only removes the icon but also removes the notification itself?
