'Chime on Homepod' not working
**Describe The Problem:**
In IOS 14, if you go to Notifications on Homekit for a camera that has `doorbell` set to true, an additional option is shown - Chime on Homepod.

If you try to toggle it on for a camera setup using this plugin, it says 'Could not complete operation'

**To Reproduce:**

1. setup a camera with `doorbell = true`
2. go to Settings\Notification of the camera in Home.app.
3. try toggling on 'Chime on Homepod'

**Logs:**
No error shown on HOOBS log file. It appears to be something on the Homekit side...
