Is There A Script To Fix My Chat Bubble Not Showing Up In Game?

So I have been trying to fix this thing where you join the game and you say something in the chat and it only shows up in the chat dialogue and not on top of my head. Is there any way to fix this or a script to fix it?

Heres some code I've used but it hasn't worked:

local Chat = game:GetService("Chat")
local function setUpChatWindow()
    return { BubbleChatEnabled = true }
end
Chat:RegisterChatCallback(Enum.ChatCallbackType.OnCreatingChatWindow, setUpChatWindow)

Please help!
