Disable share functionality in Android SDK

Hello there, I’m rolling out video chat in my app and am very close to being done however there is one outstanding issue: how can I disable the share video URL icon on the UI?

I’m using these options to try to disable it, but it does not seem to work:

     JitsiMeetConferenceOptions options = new JitsiMeetConferenceOptions.Builder()          
          .setRoom(url)
          .setSubject(" ")
          .setFeatureFlag("chat.enabled", false)
          .setFeatureFlag("invite.enabled", false)          
          .setFeatureFlag("calendar.enabled", false)
          .setWelcomePageEnabled(false)
          .build();

Also trying to change the “Fellow Jitser” message to my own custom string, but not seeing any support for that, that would be a bonus question.

Thanks!
