How do I make prop_static a button?

I’m making a map, and I have a garage door. I want it to be opened by pressing e on a prop static. How could I achieve this?

Despite this being in the wrong section, I’ll help.

Make a nodraw box around the button prop. Make it a func_button (ctrl+t if you don’t know, but you should) and choose the setting you want. Add a OnPressed output that targets your garage door to open.
