How to configure motion notification through HTTP or SMTP?
I want to try using my camera's built in-motion detection but I'm struggling to understand how this should be configured. My camera is configured, shows up in HomeKit, and I do receive motion notifications for videoanalysis triggers in HomeKit, but I want to see if I can get the camera's built-in motion notifications enabled instead.

My camera has SMTP notification enabled and successfully sends messages through a gmail account. However it's unclear how to configure camera.ui to catch this notification and forward to HomeKit. I've tried plugging in the same to/from email accounts in the camera alarm SMTP settings but that doesn't seem to catch anything.

I believe my camera has HTTP motion detection stream as well, but the HTTP alarm fields in camera.ui are disabled, even though I have HTTP enabled and showing as online under the main system settings section.

I'm running homebridge-camera-ui@5.0.14-beta.0 on a Mac.
