Opening gate with Ring doorbell 2 or video doorbell pro

Hi, I have an intercom that uses [electric strike ](https://en.wikipedia.org/wiki/Electric_strike) to open an external gate. How can I connect a "Ring Doorbell 2" or a "Doorbell Pro" to open the gate through the ring app? ps: Electric Stike normally works by sending 12v into the lock to open it.
