In the editor, place down a Side: Empty, Class: Object [Furniture], Unit: Desk. Place a Side: Empty, Class: Object [Small], Unit: Laptop (Open), 1.5 meters elevation so it falls on top of the desk. Place a Side: Empty, Class: Object [Small], Unit: File (Top Secret), 1.5 meters elevation so it falls on top of the desk.
I rotated the laptop and file so the corner stuck out the edge of the desktop, otherwise you won't see the keyboard or file at all.
