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()          
          .setSubject(" ")
          .setFeatureFlag("chat.enabled", false)
          .setFeatureFlag("invite.enabled", false)          
          .setFeatureFlag("calendar.enabled", false)

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.
