Allow custom group chats in games.
Allows a player to add and remove players from a group chat within the game, similar to the team chat feature, but players can be added or removed from the chat by the player that created the group chat . This would be helpful in
diplomacy games where one or more coalitions have been established. Currently, our best option is Discord, but not all players want to join a discord server, so it's not always effective, in which case, we are forced to share the same messages with each player individually, and often this makes communications very slow, it's a race against the boot timer just to ferry responses between players, and it's especially tedious when discussing important issues which then require a subsequent vote of all coalition members.
