This support, however, is disabled by default and you will have to manually enable it. If you are wondering how to do that, here are the steps:
Open Google Meet through apps.google.com/meet/
Click on ‘Join a meeting’ or ‘Start a meeting’ as per your requirement
Once inside the meeting room, look for three horizontal dots on the bottom right corner of the screen and click on it
Click on ‘Change layout’
Among the four options that you see, click on the ‘Tiled’ layout
From the bottom, drag the slider to the extreme right to set the number of tiles to 49
Now you will be able to see 49 people on your screen at the same time. Readers must note that this feature is only available in Meet on the web. By default, the maximum number of tiles you’ll see in auto layouts is 9, and in tiled layouts is 16.
