Insta 360 Link Support

[jorgecastro05]

The Insta 360 Link webcam, works as expected with gimbal, brightness, contrast, saturation and sharpness controls, but is missing the controls related to exposure, the official application for windows systems support manual and automatic exposure, so I would like to add these controls with cameractrls.

Is there any developer guide, or starting point to find the exposure controls, not available using the v4l2-ctl, or some way to search these parameters, and adding manually to cameractrls?
