edX is deprecating the edx_zoom xblock. The edx_zoom xblock is defined at GitHub - edx/edx-zoom: Zoom XBlock.
The xblock was a beta testing feature leveraged by limited set of courses to use Zoom to run live meetings and presentations.
Currently, there is no more active running courses using the xblock.
The xblock is already marked disabled and deprecated on edx.org LMS and Studio.
Please reach out to me and/or this thread if you have concerns or questions
