How to tell Steam what our player is doing?

As stated above, I’d like to tell Steam what our player is doing at all times, whether he is in the main menu or in a game and more. Such as if someone goes to their friends name and clicks, “View Game Info” and they get told what they’re doing.

I’ve noticed other games can accomplish this if they are in a dedicated server, but I haven’t found it for just peer-to-peer networking if it’s allowed. I thank you for your help in advanced!

Figured it out.
