Push notifications: GCM replaced by Firebase Cloud Messaging

I'm trying to implement push notifications in our app, but I see that all Mendix documentation is based on Google Cloud Messaging, which according to Google has been replaced by Firebase Cloud Messaging. The documentation is therefore not up-to-date nor correct anymore, so I was wondering if the module & widget are still fully functional and whether it still makes sense to follow the Mendix documentation?

Found it out myself, it still works. You can just use Firebase and search for the Project ID (Project Settings) and existing API Server Key (Project Credentials).
