Using Stride, how do I share my entire screen, not just specific, single applications?

1. I want to share my entire screen during a meeting, not just a single application.

2. I need to work on what I am sharing.  currently the Stride screen blocks the app with focus.

I just figured it out.    The web app version of Stride does not allow full screen sharing... only specific applications.  The downloadable app version DOES allow full screen sharing.  However, it has a cascading screen sharing effect when you share the shared screen sharing the shared screen, etc.
