How can I manually open the trunk of my Audi A5?

I recently purchased an Audi A5 and I can't seem to find a button or lever to open the trunk manually. I've tried using the key fob and the button inside the car, but neither seem to work. Does anyone know how to manually open the trunk without using the electronic methods?

You can use the key to manually unlock and open the trunk. Simply insert the key into the keyhole located above the license plate and turn it to the left to unlock the trunk. Then, push up on the handle above the license plate to open the trunk.
