In A-Frame 0.8.2-AR.js When We Load Big 3D Model,It Takes TimeToLoad The Assets(Resources) & Render The Resources,So I Want To Show A Loading Screen

When We Load A Big 3D Model Or Big A Video, It Takes Time To Load The Assets(Resources) And Render The Resources,So I Want To Show A Loading Screen Or Loading Gif File or a Loading A-Box - Till The Whole Assets Loading And Rendering Is Done,On The Screen Or On The Pattern.Please Go Through My GLITCH , Its Working But It Will Take 10-15 Sec to load and render.

I tried To Add Asset Loading Manager But It didn't Worked . I Tried All The Ways But It Didn't Worked

         </a-marker>
         <a-entity camera></a-entity>
         <a-entity shadow="cast: true"></a-entity>
      </a-scene>
      <script>
         // Workaround for an AR.js bug (https://github.com/jeromeetienne/AR.js/issues/410)
         const sceneEl = document.querySelector('a-scene');
         sceneEl.addEventListener('loaded', () => {
           sceneEl.camera = new THREE.PerspectiveCamera();
           scene.add( camera );
         });
      </script>
   </body>
</html>

After Showing The HIRO Pattern Its Takes 10-15 Seconds (Depending Upon The Internet Speed) To Load And Render . I Want To Show Some Preloader Or Loading Screen Or Some Gif Loading Image To Display Till The Object (Assets) Loads Completely And Render ......

Thanks In Advance
