i'll make an answer of my comment for readability :

For infos , if clip-path is used on a 2 level container, it is possible to add a shadow around the translucide edges with drop-shadow() filter .

jsfiddle demo in the snippet below:

.test div {
  background: red;
  width: 100px;
  height: 100px;
  /* CORNERS */
  clip-path: polygon(10px 0%, calc(100% - 10px) 0%, 100% 10px, 100% calc(100% - 10px), calc(100% - 10px) 100%, 10px 100%, 0% calc(100% - 10px), 0% 10px);
}

.test:hover {
  filter: drop-shadow(0px 3px 0px green) drop-shadow(3px 0px 0px green) drop-shadow(-3px 0px 0px green) drop-shadow(0px -3px 0px green);
  /* made 1 for each sides */
}

.test:hover div {
  background: white;
  cursor: pointer;
}

.test {
  width: max-content;
}

.test div {
  /* demo purpose */
  display: flex;
  align-items: center;
  justify-content: center;
  flex-direction: column;
}
