How do I make a GUI open with a click detector? (With LocalScripts)

I knew that you can't open a GUI with a LocalScript, but I tried to do it in several ways anyway; and actually, it can't be done. But you can do it with a Script, and it will only affect the player and won't affect others (only the GUI will appear for the one who pressed ClickDetector). This is the best way to do it:

script.Parent.MouseClick:Connect(function(player)
    player:WaitForChild("PlayerGui").ScreenGui.Frame.Visible = true
    --Reminder: Change the names and locations to the ones you need
end)

It's a very simple stuff. Let me know if this answer helped you :D
