Getting started with Unity and Oculus Quest 2 VR development

While there are lots of YouTube videos on the subject, many are out of date.  I have questions:

1.  On Windows 10 Home (MacBook Pro w/Bootcamp), I have Unity and the official Oculus Link cable.  Do I have to build and run each time or can I play the scene to view on my OQ2?  When I do try to run it, I see three dots in the OQ2 and it seems to hang.  The Link app is not running.  Under macOS, this worked fine.

2.  What about EditorXR?  I have difficulty with 3D perspectives.  Working with Unity in VR would be a major productivity leap.  Does EditorXR work on Win and macOS?
