Gate Soft Button overlaid on Camera Feed

Hi. We have a sonoff camera at the gate and we have a sonoff gate controller connected to the gate motor. I would like to know if it is possible to add a soft button ON the LIVE camera feed so that when my visitor arrives, I can press the soft button to open the gate as well as close the gate. I think that a script might need to be written but I am not the best at coding. If someone can give me an idea on how to do this…it will be excellent. Thanks team

eWeLink offers the feature in the reverse way, just pin the camera to the rollers on the device page to get the live view.

Excellent Heisenber. Will try that. Thanks
