Changing the video layout (Speaker view and Gallery view)
To switch the video layout during a meeting, click the "View" icon at the bottom panel.
The view layout will change accordingly from speaker to gallery mode or back.
Speaker view will switch the large video window between who is speaking.
Gallery view lets you see thumbnail displays of participants, in a grid pattern, which expands and contracts as participants join and leave the meeting. When in Gallery view and a participant begins speaking, that active speaker is marked with blue frame, making it easier to recognize who is speaking.
