android - Clarify the Firebase connections

Question

I am a little confused about the Firebase pricing model, special concern is the connections or more precisely concurrent connections.

Let's have an example of a mobile app for iOS called FanZONE:

User will create groups during football matches. They will comment on the actual game and the comments are immediately displayed on each members screen.

Does this scenario means that each user who is participating on commenting/viewing counts for one connection?
So if a group contains 100 users who actively follow the screen and from time to time comment is there 100 connections each 90 minutes long?
What about users who have the app in the background and the app checks each 5 minutes the score. Is this connection as well 90 minutes long or only a fraction of time every 5 minutes?
