Have you tried rendering any of the examples in the repo? I know its not ideal but just to see what is going on. Please add an issue on the repo so I can try to fix the issue you are experiencing.
I can open an issue but there isn't anything more than 'doesn't work' I can add. If you can describe some way for me to get information that's useful to debug, I can write that up.
In AutoCAD and Fusion 360 it's bound to double-click middle mouse because of how often it's used, though between users of 10 different 3D software packages you'll find 10 different but strongly held opinions on how the viewport navigation should work.
