How do you create a message-like UI, visible for everyone?

Hello,

So, I have been trying to make a custom UI that pops up when using Merely's Soft Shutdown Reset script. He is using a message, but that is hidden beneath other UI. I want it to be above all other Screen Gui's, messages are also deprecated.

Help is very much appreciated. I have been trying different solutions for two hours. When trying to explain how your solution works, simply make a ScreenGui with a TextlLabel. That will be enough for proof of concept. :)

local TeleportService = game:GetService("TeleportService")
local Players = game:GetService("Players")

if (game.VIPServerId ~= "" and game.VIPServerOwnerId == 0) then
	--[[ I want to insert a TextLabel visible for everyone here.
	local m = Instance.new("Message")
	m.Text = "This is a temporary lobby. Teleporting back in a moment."
	m.Parent = workspace
	]]
	local waitTime = 5
	
	Players.PlayerAdded:connect(function(player)
		wait(waitTime)
		waitTime = waitTime / 2
		TeleportService:Teleport(game.PlaceId, player)
	end)
	
	for _,player in pairs(Players:GetPlayers()) do
		TeleportService:Teleport(game.PlaceId, player)
		wait(waitTime)
		waitTime = waitTime / 2
	end
else
	game:BindToClose(function()
		if (#Players:GetPlayers() == 0) then
			return
		end
		
		if (game.JobId == "") then
			return
		end
		--[[ I want to insert a TextLabel visible for everyone here.
		local m = Instance.new("Message")
		m.Text = "Rebooting servers for update. Please wait. Don't worry, your data is saved."
		m.Parent = workspace
		]]
		wait(2)
		local reservedServerCode = TeleportService:ReserveServer(game.PlaceId)
		
		for _,player in pairs(Players:GetPlayers()) do
			TeleportService:TeleportToPrivateServer(game.PlaceId, reservedServerCode, { player })
			while (#Players:GetPlayers() > 0) do
				wait(1)
			end
		end
	end)
end
