I try to add elevation(shadow) to a MUI Avatar component https://material-ui.com/components/avatars/#image-avatars.
<Avatar alt="Cindy Baker" src="/static/images/avatar/3.jpg" />
Wrapping the Avatar with paper or Card increases the radius.
I also tried setting boxShadow of the Avatar using makeStyles and MUI shadow https://material-ui.com/system/shadows/ but without success.
