Unity sample for Camera2 API to capture image from CV/Main camera

This was just asked by another developer, is it okay if we move the conversation here:

Unity sample for Camera2 API to capture image from CV/Main camera

As MLSDK being deprecated, we are trying to migrate MLCamera to Camera2/OpenXR APIs in our Unity application. We found support on Pixel Sensor only which does not support any RGB cameras, and we do not find any references for Unity to access Camera2 APIs to obtain the image, intrinsic, and extrinsic data. Will there be a sample on how we could retrieve such data with the new API?
