I don’t do VR.
But, sliding the mouse does change the view by default.
Cockpit Interaction X &Y Axis is mapped for the mouse slide
(Up, D, R, L).
I can click the right button or middle button to display the cursor.
Then, left click works.
Be sure they are blue to be able to click them and work.
Note:
Mouse Right Button is Character Cursor Mode Set.
Middle is Character Cursoe Mode Toggle
