Android - Leave Event - Not Trigger

Have used Jitsi Meet SDK in Android app.

How can I detect User Leave?

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_meeting);
        
        URL serverURL;
        try {
            serverURL = new URL("https://meet.justlearn.com");
        } catch (MalformedURLException e) {
            e.printStackTrace();
            throw new RuntimeException("Invalid server URL!");
        }
        JitsiMeetConferenceOptions defaultOptions
                = new JitsiMeetConferenceOptions.Builder()
                .setServerURL(serverURL)
                .setWelcomePageEnabled(false)
                .build();
        JitsiMeet.setDefaultConferenceOptions(defaultOptions);

        JitsiMeetConferenceOptions options
                = new JitsiMeetConferenceOptions.Builder()
                .setRoom(Constants.roomUrl)
                .build();

        JitsiMeetActivity.launch(this, options);
    }

// Not Trigger
public void onConferenceLeft(Map<String, Object> data) {
startActivity(new Intent(MeetingActivity.this, LoginActivity.class));
}
