Playstation move controllers

I'm looking for a way to get the orientation of Playstation Move controllers via a web browser. I can get button presses via the Gamepad API but it doesn't seem like the controllers get detected as WebXR input devices, I assume this is due to browsers not expecting this device type?

I'm using this application to pair the controllers https://github.com/thp/psmoveapi <https://github.com/thp/psmoveapi>, so I might be able to "trick" browsers into seeing the Move controllers as a supported device, but I can't find any information on how browsers are doing this detection-- and this might not even be the problem. If anyone has some guidance on how I might could make this work, it would be much appreciated.

Thanks
