firebase - Using a listener after an android application is closed

Question

I've just been reading about adding a service to my application, and since 7/8 there are now service restrictions to improve phone performance.

I've seen that the recommended approach is to use a job scheduler, but will that not just periodically start a new listener if I did that?

Basically I update my database, and using a snapshot listener I want to update my user in real time. When the app is closed, I'd like to send a notification.

My issues (if I'm correct) are that constantly making a new Firestore request will eat through my request allowance.

Also, if its a job scheduler it won't quite be real time?

I've read that you can use a foreground service, but this doesn't really seem like that task that needs a permanent notification and would annoy the user.

Anyone got any tips on how I'd implement this?

Thanks
