Need to share a game.

So we plan to have multiple masters for big campaign. How can I give GM access\control of an existing game? I'm not really familiar with roll 20 and didn't find any way to do it except sharing my account wich is not an option.  If players could at least see any of the campaign tabs at any moment that would do the trick (But I'll have to share control of so many tokens wich makes me sick). And again I can't find any settings wich would give me that option. 

You can promote joined players to Co-GM status in the Game Settings for a Game, see here for more details:&nbsp; <a href="https://wiki.roll20.net/Game_Management#Joined_Pla" rel="nofollow">https://wiki.roll20.net/Game_Management#Joined_Pla</a>...

Oh thank you so much! I've used Shared link to join players and that was a problem. Should've guessed that's the case
