I have an app that uses Zoom macOS SDK and it is able to start meetings and share the screen when running by itself. However when I’m in a meeting and sharing screen in Zoom client, I’m able to start a meeting in my app but not share the screen. It works fine when using Zoom’s meeting UI - screen sharing stops in the Zoom client and starts in the app, but when using custom meeting UI, I just get an error when trying to start screen sharing programmatically.
Hi @santhoshr048, thanks for the post.
Unfortunately this is not yet supported when using a custom UI. We plan on adding this in a future release, so be sure to keep an eye on our release notes. 
Thanks!
