Sharing Lightbox view via Remote app or other means?

Been trying to find a clever way of sharing the lightbox view with a client during a remote working session, but so far no solution. I can send the lightbox to my CC monitor & projector in my studio obviously with Send->SDI, but if I am working via zoom, for discussion, and client is reviewing the color work viewer through Blackmagic Cloud App at their site, it would be amazing to be able to share the lightbox in realtime to discuss shots in context with neighboring shots. Has anyone figured out a way to accomplish this, other than screen grabbing the lightbox, and importing as a temp clip (obviously not a very accurate CC workflow). -Thanks for any suggestions.
