I mean you want to make your script not close itself right ok let me make a template for you.

function Main()
	debug = -1
		local menu = gg.choice({
		"Super Hack 1";
		"Super Hack 2";
		"Super Hack 3";
		"[  ] Exit";}, 0, "the super script")
		if (menu == nil) then gg.setVisible(false) gg.toast("you canceled the dialogue")
		elseif (menu == 1) then SH1()
		elseif (menu == 2) then SH2()
		elseif (menu == 3) then SH3()
		elseif (menu == 4) then os.exit()
		end
end
function SH1()
	debug = -1
	-- Do some stuff
	-- You can also add a sub menu if you  want
	gg.alert("Super Hack 1")
end
function SH2()
	debug = -1
	-- Do some stuff
	-- You can also add a sub menu if you  want
	gg.alert("Super Hack 2")
end
function SH3()
	debug = -1
	-- Do some stuff
	-- You can also add a sub menu if you  want
	gg.alert("Super Hack 3")
end
--== Script config
while true do
	if (gg.isVisible(true)) then
		gg.setVisible(false)
		debug = 1
	end
	if debug == 1 then Main() end
end
