I am posting this because it is hard to find Information on how to change the chat type in game places now days… So here is how it is currently done. In Roblox Studio go to the command line while game is not in run or play and enter one of these commands and hit the Enter key. Then select Players in the Explorer window and look in the Properties window to see which chat types are enabled or disabled for this place.
game.Players:SetChatStyle(Enum.ChatStyle.ClassicAndBubble) – will enable both chat types
game.Players:SetChatStyle(Enum.ChatStyle.Classic) – will enable just Classic chat
game.Players:SetChatStyle(Enum.ChatStyle.Bubble) – will enable just Bubble chat
