React native iOS how to make background process after getting new remote notification, without opening the app

I use react-native-firebase to get remote notification, and i want after getting remote notification(data-only) to do some process in background, without opening the app (without tapping on the notification).

• I achieved that in android with Headless JS.

• I really want to find how to do that in iOS

I read about:

1. Notification Service Extension - https://developer.apple.com/documentation/usernotifications/unnotificationserviceextension

2. https://github.com/react-native-webrtc/react-native-voip-push-notification

But I didn't get it to work, maybe someone has experience with this situation?
