Jitsi for Flutter with limited feature flag

I had integrated Jitsi Meet SDK with my flutter application but how can I set a specific person as a moderator, and moreover unmute option is available to everyone how can I enable it to the moderator and disable that feature for everyone.

I had tried this approach to make someone as a moderator and unmute all, lobby mode disable and screen sharing disable is not available as a feature flag in JITsi.

if (admin == "admin") {
    featureFlag.kickOutEnabled = true;
    featureFlag.meetingPasswordEnabled = true;
    featureFlag.videoShareButtonEnabled = true;
    featureFlag.liveStreamingEnabled = true;
    featureFlag.meetingPasswordEnabled=true;
    featureFlag.toolboxAlwaysVisible=false;
