How to remove the bubble chat certainly?

Hello, I was making, like a phone system, but using like plr.Chatted, for chat, basically, I want to basically, remove the overhead gui of the chat when the player is like, talking on a call with someone, how can I remove the billboard gui or like the bubble chat avobe head?

The bubble chat should automatically be removed when you start the game. However, I think you can disable it like so…

local PlayerGui = PlayerInstance.PlayerGui
PlayerGui:SetCoreGuiEnabled(Enum.CoreGuiType.Chat, false) 

This is not what I want at all. please read

You would do something like this:

local Chat = game:GetService("Chat")

Chat:RegisterChatCallback(Enum.ChatCallbackType.OnCreatingChatWindow, function()
    return {
        BubbleChatEnabled = false,
