I cant make a admin GUI and i need help from a better scripter. Anybody willing to help?

Today i was playing my simulator and my friend joined and told me to give him unlimited coins with an admin GUI, but i didn't have one and i don't know how to script it. I have the GUI i just need a player only GUI script.

Make a local script in starter gui. Make a list of admins like this -

local admins = {'Name', 'Name', 'Name'}

Then check if they are in the list, I think this will work

if game.Players.LocalPlayer.Name not in admins then
	script.Parent.GuiName.Enabled = false
