White - Dark bubble chat

[KDBgames]

I want to make a dark chat and a light chat. but it will not change like I want it to do.

But I still have a white bubble chat:

-- This is my code
local Chat = game:GetService('Chat')

-- Set default chat settings
Chat:SetBubbleChatSettings({
	BackgroundColor3 = Color3.fromRGB(15, 15, 15), 
	TextColor3 = Color3.fromRGB(239, 247, 255)
})

I already looked online, but I did not find anything on the roblox creator forum
link: Chat | Roblox Creator Documentation

I do not work anymore sinds I use the NEW ChatVersion:

Can someone help me please? THANKS!

The script should be client-sided and I suggest to put it inside StarterPlayerScripts.

This actually doesn’t fix anything, I have the same issue. I actually tried almost everything but nothing seems to work.

local bubble = game:GetService("TextChatService"):WaitForChild("BubbleChatConfiguration")
bubble.BackgroundColor3 = Color3.fromRGB(15, 15, 15)
bubble.TextColor3 = Color3.fromRGB(239, 247, 255)
