"Cloud Proximity Guest Share" setting & disable guest share?

[gfolens]

I found this setting under Webex on a Webex Room Kit Pro.

You can set "Cloud Proximity Guest Share" to Auto or to Off.

What happens if you set it to off? No Proximity share possible from a Webex client?

Is there a way to disable or limit Webex Proximity share for users with a Webex account/app but not belonging to the organization of the Room Device?

Seems switching "Cloud Proximity Guest Share" to off does not disable the Proximity share on a Webex Room system.
After changing it to off the share from my Webex app to the Room system is still working...

This setting allows you to turn off the guest share feature via devices.webex.com only
