title: How to add a multiple models in the viewer?
body: <p>I am creating a site with a forge-viewer and want to view multiple loaded models in a single window. How can I enable the function of loading and viewing several models in one place?</p>
  
  <p>This is for a new site. I have already tried all the methods and recommendations available on the Internet,but none of them helped me solve my problem.</p>
  
  <p>My code is fully consistent with the code from this source <a href="https://github.com/Autodesk-Forge/learn.forge.viewmodels/tree/nodejs" rel="nofollow noreferrer">https://github.com/Autodesk-Forge/learn.forge.viewmodels/tree/nodejs</a></p>
  
  <p>I expect that I can finally add the function of loading and viewing several models in one window, but so far I did not manage to do it.</p>
