Hi, I'm beginner in WebAR. I need help regarding light estimation. Please anyone can help me to add light estimation component in my webAR code.
Here's my code for simple webAR:

<script src="https://aframe.io/releases/1.4.2/aframe.min.js"></script> <script src="https://cdn.jsdelivr.net/gh/donmccurdy/aframe-extras@v6.1.1/dist/aframe-extras.min.js"></script> <script src="https://cdn.jsdelivr.net/npm/mind-ar@1.2.2/dist/mindar-image-aframe.prod.js"></script>

  <a-entity mindar-image-target="targetIndex: 0">
    <a-box
      position="0 -1 0"
      rotation="0 45 0"
      color="#4CC3D9"
      animation__yoyo="property: position; dir: alternate; dur: 1000;
                             easing: easeInSine; loop: true; to: 0 1 0"
    ></a-box>
  </a-entity>
</a-scene>
