Chromecast - show URL from camera

I have a bunch of cameras that I can tell Google to cast to my TV’s via the connected Chromecasts. What I now aim for is to set up a flow so that it automatically casts the specific camera whenever the doorbell is pressed.

I have a proper URL that works fine with a browser (which opens VLC) which includes user and PW, and I don’t know if Chromecast can handle that. Any ideas? Cameras are Reolink btw.

Try it and see.

Sorry for being unclear. I have tried that and the chrome cast logo is the only thing shown.

Always use a “stop casting” card before starting a “cast X” card.
