Doorbel trigger does not work with Unify OS Console version 1.20.0
<!-- BUG REPORTS THAT ARE NOT FILLED OUT COMPLETELY WILL BE CLOSED AUTOMATICALLY WITHOUT WARNING AND WILL NOT RECEIVE A RESPONSE. THE FORM IS HERE FOR A REASON. :). -->
<!-- Please ensure you read the documentation before creating a support request, especially the Troubleshooting page. -->

**Describe The Problem:**
I use the homebridge UniFi Protect plugin successfully to interface my devices to homekit. But the current release 1.20.0 does not activate the doorbell trigger in homekit. It is visible in homekit, and when you trigger the doorbel trigger accessoire manually in homebridge the connected device in homekit is active. But if you physically press the doorbel, all homekit messages are activated, but NOT the doorbell trigger.
**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
- Install homebridge
- install unity protect version 1.20.0
