gas tank cover question on 1998 Audi A4 Quattro

How do I open the gas tank cover? I just took over this car and I wasn't told how to open it.

The button to open up the gas flap is located on back side of the pocket of the driver's side door. It's not even close to being in sight, and it's kind of a hassle to find
