swift - Can you listen to Firestore updates when iOS app is in the background?

Question

I'm very new to Firestore and trying to understand how the real-time updates work. I'm using something like this now to get the updates from Firestore:

db
  .collection(Collections.session)
  .whereField("participants", arrayContains:userID)
  .addSnapshotListener { querySnapshot, error in

I noticed that the listener block is not getting fired when the app is in the background, but only when it's brought back to foreground.

Is there a way to get the update when the app is running in the background too? Maybe somehow send a push notification or something?

Any kind of help is highly appreciated.
