[Request] AR Tags for Quest

Not sure which developed forum this would be best to raise in (Quest, Unity, Meta Spatial SDK, or SDK) but here it goes. Ideally this would go into a suggestion box but I'm not seeing a suggestion forum here.

I would love to have the ability to use AR tags with the Quest. Having AR tags would do wonders for tracking the position of objects, people, body parts in the real world. This would be an immensely useful tool for HCI researchers, who may want to track the arm or props for a study, and game developers, who could use this to build custom physical props for their games.

I have looked far and wide on the Unity store and the web but this functionality doesn't seem supported.

Does anyone know if this is possible? Perhaps a script or an addon I can buy? I would pay good money for this.

Cheers! IA
