How do I make a GUI only appear once? It keeps coming back up every time you respawn

I'm making a game and every script I've made hasn't worked. I've made the GUI but I only want it to come up once when you first spawn in not every time you respawn.

1. Insert a LocalScript into the GUI that says Gui.Enabled = false, or put this somewhere in the code if you have it already.

In the properties tab for the GUI, there should be a property that you can tick so it only appears once
