A GUI script that enables the GUI (pop ups) Without tweening the size?

I have A event script is made to where what ever script i place below it will activated by the event. Im horrible at scripting that, i need a script that will make my gui pop(show up like transparent or something) without tweening it.

game.Workspace.MyClickDetectorEvent.OnServerEvent:Connect(function()	
	--script goes here but i dont have one 
end)

And hopefully ill be done with a paper you can click on and read with a gui pop up.

Might I suggest this video here for you:

It's a pretty easy and simple GUI set up which matches what you'd like (I think).

It's also very close to what Dinoz said in the comments - just make the Gui visible when the player clicks on it. Plus, it won't affect players' game experience.

If you don't think this is as helpful, reply to the answer and I'll see if I can help more.
