Custom XR plugin

Hello,

I am currently doing some freelance work for a company which has been developing their own glove controller with Arduino interface.
What we need is to be able to use it as custom input for the Oculus Rift headset, instead of the Oculus controllers. I am not sure if this is possible, but perhaps a Unity dev can shed some light, if a custom plugin can be written?

If this is not possible with the Unity XR system, perhaps the extending the Oculus integration would be a better idea?

Thank you in advance!
