Teams - active users in team analytics

ChrisHoardMVP Thank you for the clarification. However, I still don´t understand what actions make a user considered as active user.

I understand that some actions are considered as active and it is completely logical - e.g. starting a new post, calling etc. But what about only reading posts? Or active looking to channels, e.g. at files without editing them?

These are actions I am quite confused about - because if I have like 5 out of 10 inactive users in my team, does it mean that they do not go to the team at all? Or does that only mean that they are not actively engaged, e.g. liking posts?
