Excuse me,

Sometimes users can’t join a Zoom session with the UI Toolkit.  
When they fail to join, an error message appears in the UI Toolkit (as shown in the attached picture).

Is there an event listener to capture this error?

Looks like the JWT is invalid, that’s why you’re seeing the error.  
We don’t have a way to programmatically access the error event. I’ll share this with the team to consider adding an event listener for this in a future release.
