**Describe The Problem:**

This is a request for help. All my cameras are Unifi, the module looks without issue. My issue is I have a Grandstream Doorbell with a camera (which I connect to homebridge with another module) and that doorbell triggers my system using HTTP to notify me when someone rings the doorbell. What I would like to do is to trigger the doorbell on unifi-protect on one of the cameras (a camera that shows the front gate). Is this possible?

**To Reproduce:**

Just want to trigger doorbell from an external party. Don't care if it's HTTP or MQTT or any other.
