How can I add a colored shadow at the right inside of my hexagon?

.hex {
  width: 200px;
  display: inline-block;
  color:orange;
  position:relative;
  filter: url('#goo'); /* to get the rounded edge */
}
.hex::before,
.hex::after { /* the polygon shape */
  clip-path: polygon(25% 0%, 75% 0%, 100% 50%, 75% 100%, 25% 100%, 0% 50%);
  display:flex;
}
.hex::before{
  content: "";
  background:
    linear-gradient(50deg,transparent 10px, rgba(0,0,0,0.2) 0 calc(100% - 45px),transparent calc(100% - 44px)) 
    100% 100%/ 70% 89% no-repeat, 
    currentColor; /* Use the color defined by "color" */
  padding-top: 86.6%; /* 100%*cos(30) */
}
.hex::after {
  content: attr(data-text);
  font-size:80px;
  position:absolute;
  top:18px;
  left:18px;
  right:18px;
  bottom:18px;
  background:#fff; /* this should match the main background */
  align-items:center;
  justify-content:center;
}
