Your first multicast push message using FCM topics
With FCM topics, you can send messages to specific groups of app instances,
ideal for publicly available content like weather updates. Learn how to
subscribe (and unsubscribe) users from your mobile app, send multicast push
messages using topics, send messages to a combination of topics using topic
conditions, and manage topic subscriptions on the server side, including bulk
subscriptions and unsubscriptions.
