css - How to Rotate Clip Path without rotating image?

Question

I have an image with CSS property clip-path. I have added animation to rotate the clip path. I want to only rotate clip-path, not the image. From below code, you can get an idea of what I want to achieve. I did this to give you an idea of what I want to achieve. The problem with my code is that it takes a lot of time of manually set clip-path points on each keyframe. So Is there any short method to achieve the below code result without changing the points manually on keyframes? I want it to be smooth, which is pretty hard to set with manually setting the points. (Keep in mind, I don't need that last animation which makes the image invisible, I am unable to figure out why it's happening.

#profile-img {
    width: 15%;
    margin: 5%;
    -webkit-clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);
    clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);
    animation: clipRotateAnim 2s linear infinite;
}

@keyframes clipRotateAnim {

Use the image as a background of a pseudo element and rotate it in the opposite direction:

.image {
  width: 200px;
  height: 200px;
  margin: 20px;
  clip-path: polygon(20% 0%, 0% 20%, 30% 50%, 0% 80%, 20% 100%, 50% 70%, 80% 100%, 100% 80%, 70% 50%, 100% 20%, 80% 0%, 50% 30%);
  animation: clipRotateAnim 2s linear infinite;
  position: relative;
  overflow: hidden;
}

.image:before {
  content: "";
  position: absolute;
  top: -10%;
  bottom: -10%;
  left: -10%;
  right: -10%;
  background: var(--i) center/cover;
  animation: inherit ;
  animation-direction:reverse;
}

@keyframes clipRotateAnim {
  to {
    transform: rotate(360deg)
  }
}

<div class="image" style="--i:url(https://images.pexels.com/photos/1025804/pexels-photo-1025804.jpeg?auto=compress&cs=tinysrgb&h=350)">
</div>
