How can I make a fake computer desktop?

I want to create a pretend computer desktop screen which allows the player to walk up to a monitor, click on it and then open up folders (as you would on a normal computer).

I don’t want it to look like a Windows background or anything like that I just want to have a folder that sits on the desktop that says click me and when the user clicks on that said folder it opens up a fake document with a clue on how to solve a puzzle in the game.

What would be the simplest way to do this - I’m also VERY new to unity and coding so looking for a easy way

Well there is a lot of very basic stuff involve, the easiest way would be to make it all in a canvas and use buttons to unhide panels. Just checkout some tutorials, there are tons on youtube and unity learn.
