Zoom Meeting SDK - Linux - version: 5.17.11.3885

I’m trying to detect if a join attempt used wrong password.  
I’ve started with the `meetingsdk-headless-linux-sample`. I’ve defined an `IMeetingConfigurationEvent` implementation, registered it via `meetingConfiguration->SetEvent()`, but even if I call `join` with a wrong password the `onInputMeetingPasswordAndScreenNameNotification` callback method did not get called. I’ve used the same method with the Windows SDK, there it was working.  
Should I do something in addition to make it work? Or is there a different way to detect if the password provided at join is wrong?

Thanks in advance:
