Unmount aFrame on Sveltekit

Question

I'm running an AR application inside Sveltekit with aFrame and AR.js. The augmented reality runs fine with some details. My problem is that when I exit the component (I go to another page) it stays mounted and the webcam stays on. At the moment what I do is to use the onDestroy hook and every time I exit I remove the video tag generated by AR.js. This works partially but I would like to know if there is another way to disassemble. Any help is welcome. This is my code

<script>
    //componente para sombra en camera background
AFRAME.registerComponent("apply-shadowmaterial", {
            init: function() {
              // grab the mesh
              let mesh = this.el.getObject3D("mesh");
              // keep the reference to the old material
              let tmp = mesh.material;
              // assign the new material
              mesh.material = new THREE.ShadowMaterial({ opacity: 0.1 });
              mesh.receiveShadow = true;
              // free memory
              tmp.dispose();
            }
          });
</script>
