Screen Sharing Integration Not Working

Hello There,
I have created an app using the Jitsi Meet SDK Samples called Comp Labs Meet. I have enabled screen sharing using the steps shown on https://jitsi.github.io/handbook/docs/dev-guide/dev-guide-ios-sdk#screen-sharing-integration . And I have also set the ios.screensharing.enabled flag. But the screen sharing option doesn’t show after following these steps. Please help me and help is highly appreciated. For reference I am also attaching my entire project directory compressed to zip file. You can Use that.

Regards,
Comp Labs
