I would like to add both a Notification Service Extension and a Notification Content Extension to my application.
After reading some documentation and tutorials etc. I'm not clear if the Communication Notifications capability is needed or not. If it is, should it get added to the App ID or the notification IDs, or both?
Communication Notifications is not required for these extensions.
As long as your notification has visible content, the extensions will run.
You need the "mutable-content:1" entry in your payload for the Notification Service Extension to process the incoming notification.
