ONVIF through HomeKit Bridge

I'm trying to set up my ONVIF camera in HA through HomeKit Bridge.
Everything looks as it should be through setup:

  • Camera Stream can be selected properly
  • It asks to select which camera gives h264 stream: mine does.

But on my phone camera stream does not show up. (Every other switch, device etc. can be added, and right away showing up anytime.)
Is this a supported feature currently?

I'm curious to know, too. I tried ONVIF to Home App via HomeKit bridge a couple of years ago with no success. Instead of trying to solve it, I just used the RTSP stream via Generic Camera integration instead.
