Video Doorbell Pro integration to unlock existing electric lock on the door

Hello,My house has an existing intercom system with a buzz-in button that releases the front gate electric lock to let people in.I'm planning to install Video Doorbell Pro plus Floodlight Cam and I would like to have an option to unlock this gate right from the Ring iOS app interface.What options do I have to implement that? I have access to the buzz-in button wires and I can install a relay to shorten this circuit that releases the door. Is it possible to integrate sonoff with Ring app to have an open button?
