The overflow on the grid responsible for the user boxes has some overflow: hidden
defined that is responsible for cutting off the shadows. It´s hard to give more quality feedback/suggestions on this since this seems to be generated CSS. I´ve added the generated code here maybe it helps to pinpoint the issue.
.portal-css-pxropk {
position: relative;
display: grid;
gap: 24px;
grid-template-columns: repeat(auto-fill, minmax(248px, 1fr));
**overflow: hidden;**
padding: 24px 0px 40px;
}
