You can also enable bubble chat without forking the chat script. Create a LocalScript (preferably in ReplicatedFirst so it runs first, once and on the client - a warning/error gets thrown when ran on the server but it doesn’t actually seem to hamper the functionality of the code):
local ChatService = game:GetService("Chat")
ChatService:RegisterChatCallback(Enum.ChatCallbackType.OnCreatingChatWindow, function()
return {BubbleChatEnabled = true}
end)
I’m not sure what the bool for classic chat is, but I’d assume it’d be ClassicChatEnabled.
