Using Ring to control Electric Door Lock strikes (9v)

I use a Ring Video Doorbell 3, hardwired to my existing low-voltage chime. Works great. I also want to connect my Ring system to my existing low-voltage (9v) Electronic Door Lock Strike, as an accessory. I'd like to be able to Manually send a signal remotely from my Ring app to activate the existing Door Lock; this needs to be an approx 5 seconds 9v signal (ON for 5 seconds then OFF). How can I accomplish this? *(Note: I don't want the Ring Door Button or Motion activation to send the 9V 5sec signal and unlock my house without my knowing. I wish to be able to choose from the App or an accessory remote button to send a relayed 9V 5sec signal which releases the existing door latch. )* Thank you all for your suggestions, MartiniSF
