**Describe the solution you’d like**  
Currently, the `onParticipantChange` event in the #Zoom Apps SDK only fires when participants join/leave or change roles, but I need listen for **`screenName`** changes. The Meeting **Web** SDK `inMeetingServiceListener` event `onUserUpdate` does fire when a participant’s **name is changed**.

**Describe alternatives you’ve considered**  
The only alternative is running a timer interval, manually checking `getMeetingParticipants` and diffing against the previous participants list, but I’m unsure if that API method has a rate limit. Otherwise one would have to manually press a button at any given time to do the same type of diffing check.
