There used to be a collaborate button in my app, but it seems to have disappeared. I now see there is an API for `zoomSdk.startCollaborate`, but when I try to call it, I get an error:

This app cannot support collaborate mode

I enabled the startCollaborate API and I have Collaborate mode enabled (enable screen sharing fallback/enable play together are disabled).

Any ideas on what else to try? I can’t find this error message anywhere.
