[Vr Camera Zoom in / out]

@VibrantNebula 

I am using unity 2019,2.3f
I am using SteamVR Unity Plugin-v2.5 (sdk 1.8.19).

What I want to do is to enlarge the screen through camera zoom after simple ui activation.

[Vr Camera Zoom in / out]

I want to create a camera 'zoom in / out' function through a controller.
I tested the existing camera approach 'fieldOfView', the ability to move simple objects, but it didn't work.

The user remains, but is the camera's field of view adjustable via the controller?
