Collaboration in Unity with the Microsoft Hololens 2

Hi,
I'm doing my bachelor project with the Microsoft Hololens 2, specifically I'm doing a technical analysis regarding the different toolkit/plug-ins/software available for doing collaboration (not remote collaboration but local).

I'm especially looking for some that work with unity as this is the software I'm using to build/deploy my applications on the Hololens.

Here's is some of my research, if you have comment regarding it or you maybe think that it can be good to add something I would gladly discuss it with you.



As you see did find all unity supported plateforms, so even if it's not for unity I will gladly take your recommandation.

Best regards
