Grouping Friends
Using Rich Presence you can make a group of friends appear together on the friends list.
To do this you set two key values, steam_player_group and steam_player_group_size.
var MyTeamName = IsTerrorist? "terrorist" : "counter-terrorist";
var teamSize = player_list.Count( x => x.IsTerrorist );
SteamFriends.SetRichPresence( "steam_player_group", MyTeamName );
SteamFriends.SetRichPresence( "steam_player_group_size", teamSize.ToString() );
