It's now possible for the moderator to share their screen during a moderated study session.
All moderated tests begin as a face to face between the moderator and the tester.
To start the session and recording, first click "begin recording".
When ready to start the screen share, the moderator will click on the Start screensharing button at the bottom of your screen.
You will now have a choice to request permission to share the test participant's screen, or to share your own screen:
Chrome will then prompt you to select what you would like to share (entire screen, application window, tab).
