How to make a GUI Gamepass Universe Teleporter?

They've had one of these games when you press play and then it teleports you into another place, could someone teach me how to do that? I can't seem to get my head around it. Thank you.

--Place This script in the part
--This is a normal script

-- and you must have a place the place you want to teleport in your main place so the first 
--place you go to is the main 
-- game so the game where you have this place stored you must put the destination in this you 
--can do this by going under
-- Your game the 3 dots and configure I'm pretty sure
 
-- Touch Script

function onTouch(hit)
	local plrc = hit.Parent
	local plr = game.Players:GetPlayerFromCharacter(hit.Parent)
	local TeleS = game:GetService("TeleportService")
	local place1 = theid
	local place2 = theid
		if plr then
			if place1 then
				TeleS:Teleport(place1, plr)
		end
	end
end
script.Parent.Touched:connect(function(onTouch)

-- Click Script(gui)
-- This needs to be a normal SCRIPT not a LocalScript
plr = script.Parent.Parent.Parent.Parent -- This should be the player make sure you keep 
-- going up by parents so you touch
-- just make sure it is the parent of the screengui

script.Parent.MouseButton1Click:connect(function()
	local TeleS = game:GetService("TeleportService")
    local place1 = theid
 	local place2 = theid
		if plr then
			if place1 then
				TeleS:Teleport(place1, plr)
		end
	end
end

If this does not work tell me and I will try and resolve it if it works accept the answer
