Use the Zoom feature in the bottom-left portion of your screen to adjust your viewport and see more or less people around you.
Zooming In and Out
There may be times when you want to see more people around you or create a more intimate group within the Room. To do this, you can use the zoom feature located on the bottom left-hand side of your screen to zoom out and see more of the Room or zoom in to focus in on the group immediately around you.
You can also enable Auto Zoom. This will adjust your viewport automatically as the group grows or shrinks.
