Which ARFoundation Object Tracking provider-specific assets should I use for HoloLens2 ?

Hello everyone.
In the documentation of the ARFoundation Object Tracking it's written

You will need to then populate the reference object entries with provider-specific assets. Refer to the provider's documentation for instructions on how to do this.

I would like the link to the Microsoft Documentation for instruction how to do this on HoloLens2.
Maybe it could be usefull to put the link on this documentation page, with the link for iOS & Android too.

Thank you.

 

As I can see here it seems that Object Tracking works only with iOS ? If it's true, why it is not written on the Object Tracking Documentation ?
