How to send Notifications to multiple users after an Event happened?

Question

Hey I'm new to android and i made an application that enable the user to upload a file (Professor) so that Students can download it for educational purposes.

I came to point that i want when the professor upload something to the application, I need the application to send a notification to the users notifying them that a new File is ready. I'm using Firebase and I want to know if there is an easy way to achieve that.

If you're using Firebase Database along with FCM, you could make use of Cloud Functions for Firebase. Specifically, the Database Triggers.

Say, the professor uploads a file (maybe using Firebase Storage) you could have a trigger set to a node (e.g. uploaded_files) that will send push notifications to those specific users -- where I think making use of Topics sounds good here (students could star a Prof to subscribe for updates).

Simple and direct to the point.
