Jitsi SDK attempts a new connection when "Ongoing meeting" notification is touched

I have used an inherited class of JitsiMeetActivity in our Android app. The purpose is to do some processing when user selects “Back” button in phone prior to disconnecting the call. It works fine but an issue we face is this -
If user selects “Home” and then tries to re-open the conference screen by touching the notification “Ongoing meeting”, Jitsi SDK is trying to make a new connection to that conference. If I use the base JitsiMeetActivity, then I am able to re-open the conference screen.

I guess I am making some mistake in the subclass, please let me know what I might be doing wrong. Appreciate your help.

public class MyJistiMeetActivity extends JitsiMeetActivity {
public void onBackPressed() {
