G4 Doorbell no longer chiming HomePods
**Describe The Problem:**
Since updating to v6.4.0+, my UniFi Doorbell G4 is no longer making any of the three HomePod Mini's in the house chime.

All devices have been restarted, my USW and UDM-Pro have all been restarted and POE power cycled, all iOS devices and HomePods are up to date. HomeBridge is on the latest version 1.6. 

The camera and audio feed can be seen in the Home App no problem, and the HomePods have the option to enable or disable chime (which I have cycled) but no chime ever comes through to them.

**To Reproduce:**
Push the doorbell button, only the UniFi protect app is triggered, no chime occurs on the HomePods.


**Environment:**

* **Homebridge Version:** 1.6
* **Node Version:** v18.15.0 (was on 16.9, updated to see if part of issue)
* **Homebridge-UniFi-Protect Plugin Version:** v6.4.1
* **UniFi Protect Version:** 2.2.1
* **UniFi Protect Controller Type:** UDMP
* **Apple Device and iOS / macOS / iPadOS / tvOS Version:** iOS 16.4.1 (iPhone/HomePod) Apple TV 16.4
