Trouble adding UIStroke to Bubble Chat

I want to edit the default bubble chat system by adding a UIStroke to it, but im not sure how to implement it (let alone know if it’s even possible)

local Players = game:GetService("Players")

local settings = {
BubbleDuration = 15,
MaxBubbles = 3,
BackgroundColor3 = Color3.fromRGB(150, 108, 140),
TextColor3 = Color3.fromRGB(233, 174, 232),
TextSize = 16,
Font = Enum.Font.FredokaOne,
Transparency = 0,
CornerRadius = UDim.new(1, 0),
TailVisible = false,
Padding = 8, 
MaxWidth = 300, 
VerticalStudsOffset = 0,
BubblesSpacing = 6,
MinimizeDistance = 40,
MaxDistance = 100,
}

pcall(function()
game:GetService("Chat"):SetBubbleChatSettings(settings)
end)

Unless there is a hidden setting for it or you’re using the old bubble chat, it’s probably not possible because the new bubble chat frames are parented inside CoreGui.

As far as I understood from some research, it is not possible.
