Can the FCM implemented by microG wake up apps that have been killed?

This exposed module allows Google's native FCM to wake up killed apps.
Does the FCM implemented by microG also have similar functions?

Yes, force-stopped applications are woken up by microG when the app receives a cloud message through GCM.

Obviously it works only if microG GmsCore is installed as privileged application.

I've installed microG to the /system/priv-app folder using magisk, is that enough？
