VIVE Open XR with Unity

[Papa J]

I'm trying to get VIVE Open XR (AIO) working with my Unity 6 project.  From the looks of it this is a fools errand.  From the documentation is says this about version 2.4.2:

Requires Unity 2021.3.31 or newer
Requires Unity XR Hands 1.3.0. Should NOT use other version. - AIO only.

So the newer doesn't work because Unity 6 and Unity XR Hands 1.3.0 is not an avaible choice for me.

 

My question is, what is the best version of Unity to use with the XR Elite at this time?
