OSL Camera OCTANE Render not work

How to properly setup OSL Camera for OctaneRender in blender?
I’m trying to follow this instruction But the OSL Camera is not responsive and does not affect the rendering result.

If you have, can you show a working example of using OSL Camera for OctaneRender in blender?

Thank you for not leaving my question unanswered.
I have a need to use OSL Camera for Octane Render. I would like to do in Blender+Octane+OSLCamera the same as I did in Cinema+Octane +OSLCamera https://www.youtube.com/watch?v=lpp2MyjmMDk
