Automatically trigger popup camera feed

I have a Ubiquiti G4 doorbell and I want to trigger either a popup webpage or lovelace card that shows the live video feed when the doorbell button is pressed. Is this possible? Or even better, popup the live feed on an Amazon Echo Show screen.

I am not sure about amazon Echo show screen pop up but if you have the G4 video stream integrated with HA, you can popup the life feed on any browser window which is having HA. For this you would need this custom integration

The documentation is simple. You can use the new service browser_mod.command for popup.

Browser mod amazing and does a lot of things
