Stacked avatars can be used to show multiple collaborators or participants when there is limited space available. When you hover over the stack, the avatars will reveal themselves.
Avatar stack displays a minimum of 2 avatars and a maximum of 4 avatars.
Only the 20px avatar size is currently used in the avatar stack.
The default AvatarStack is left-aligned. You can right-align the component for layouts that are better suited for it.
