Meeting participants who are viewing a shared screen can switch to side-by-side mode, which allows them to see the shared screen alongside either the Speaker view or Gallery view, depending on which view they choose. They can also adjust the location of the separator between the shared screen and video to change the relative size of each side.
Tip: Sometimes when you are screen sharing, the videos appear small. You can click on the gallery icon above the videos to enlarge the videos. You can adjust further by using the corners of the videos to re-size.
