"Dont have permission" To detect change to CoreGui

[Crysta1Egg (Robloxian)]

I’m trying to Detect when an outside source is adding Non-Roblox Guis to CoreGui folder, but I get a “Do not have permission” text.

local CoreGui = game.CoreGui

CoreGui.ChildAdded:Connect(function(Child)

     print(Child,"Added Into CoreGui")
     game.Players.LocalPlayer:Kick("Hack Client")
end)

I believe there was a similar post made about this subject, you can find the answer to your question here:

Accessing CoreGui in localscript?

You can access CoreGui by doing game.CoreGui. What are you going to do with it exactly? What you said doesn’t work because CoreGui obviously is from Roblox and comes with every player, which would mean it would ban everyone.

CoreGui isn’t accessible to developers. That means you CANNOT get it’s descendants or properties.

CoreGui documentation.
