Why does this GUI's Removing Gamepass Script not work?

What this script is intended to is if you have a gamepass the NewsGui, and Ad (GUI) get destroyed.

would i need to go to the PlayerGui instead?

GPS = game:GetService("GamePassService")
player = game.Players.LocalPlayer
id = 498305418

game.Players.PlayerAdded:connect(function()
	if GPS:PlayerHasPass(player, id) then
		game.StarterGui.NewsGui:Destroy()
		game.StarterGui.Ad:Destroy()
	end
end)
