We're using Urban Airship to send push messages to our Android app.
In that process, we need to configure Airship with 'Server Key' provided in Firebase Console -> Cloud Messaging.
As recommended there, we are trying to migrate from GCM to FCM.
The problem is that 'Server Key' is missing in 'Firebase Cloud Messaging API (V1)' configuration. It is still available in 'Cloud Messaging API (Legacy)' configuration, but migration is suggested.
Following the links in FCM configuration didn't help too much with this issue.
