FF created all the configuration for Notification once I got the paid version of Firebase in Feb of this year 2023, now I keep getting email from firebase about doing migration from legacy FCM APIs to HTTP v1, do I need to do something or even the Cloud Messaging API (Legacy) discontinued my notification messages should still work because I see Firebase Cloud Messaging API (V1) is enabled and FF is using cloud function to add FCM token and send notification messages. Can someone explain me if I really need to do something? I'm super confused at this point.
