Given there's an electronic lock on the other side with a keypad, it makes me think that thing has its own actuator and didn't want to mess with it. Otherwise it would just be a matter of adding an "Electric strike?" (https://www.tesa.es/en/site/tesa/products/electromechanical-...), feed it 12/24v through a relay connected to the pi zero, and add another api endpoint
