FirebaseInstanceIdService does not exist

Karel Krýda :

I'm creating a chat app and according to the tutorial I should create this: Tutorial example

The problem is that nowadays this function (FirebaseInstanceIdService) no longer exists and therefore I cannot use it. Would anyone advise me with what code to achieve the same result? Thank you

FirebaseInstanceIdService has been depracated and replaced with FirebaseMessagingService

onTokenRefresh is now onNewToken.
