HA trigger script on another PC

Hi have HA running into docker on a Synology nas. In the kitchen I have a general purpose computer that serves as a tv, web browser, etc.

I currently have an automaton for the doorbell- when pressed, make a doorbell noise on xiaomi speaker and IM my phone. I’d like to add for the kitchen computer to display the front porch webcam also.

I have a script on the kitchen windows machine to open and start streaming the porch webcam, but any clues how I would go about triggering this script from HA?

Maybe I need to make a small python web server and use a rest call to an internal endpoint
