Push Notification on Android

Hi all,

I tried to follow the steps in https://www.mobile-coach.eu/docs/installation/pushnotification to set up push notification on Android. The legacy server key from Firebase is needed. However, from March 2020, FCM has stopped creating legacy server keys. (reference: Release Notes  |  Firebase)

Please suggest what should be done to support Push Notification on Android for new project, thanks.

Best regards,
