Transparency not working on conversion from fbx to glb (draco compressed) in browser based viewers.

[parassrivastav]

I converted an fbx file (download here) into glb file (resulting file is here) using fgxtogltf npm as follows

const convert = require('fbx2gltf');
convert('Mercedes_Benz_GLE_class.FBX', 'enzo.glb',['-d']).then(
  destPath => {

  },
  error => {

    console.log(error);
  }
);

The resulting glb looks like following in blender

But same glb looks like following in donmccurdy or babylonjs

How do I get alpha blend transparency to happen in web based browsers?
