Hie, I have a project that uses FCM (Firebase Cloud Messaging) for notifying the app of data that was updated, created or deleted. The payload includes enough data on what on either of those 3 above mentioned operations then updates my core data entities. This unfortunetly only works if the App is in the foreground, but I can't for the life of me find out how to do it in the background. What I need is for the app to update my core data entity even if the app is in the background state when it receives a notification.

My plea is, does anyone have a guide that shows how to trigger/run any tasks in the background after receiving a notification from FCM. Any minimalistic application of that would work for me then I can attempt to implement it from my end.
