How to customize my own tracker to work with OpenXR games?

[TitansWhale]

I have written my own driver to upload a tracker following the instructions on https://github.com/terminal29/Simple-OpenVR-Driver-Tutorial. I found that my driver works perfectly in VRChat, but it fails to recognize my custom tracker in Blade and Sorcery. As far as I know, B&S uses OpenXR, while VRChat uses OpenVR.

I believe the issue is that my driver is not compatible with OpenXR games. how to modify my driver to be compatible with OpenXR games?
