I need that URL to be downloaded and converted to a .glb on my computer, then imported into AE.

@ShiveringCactus 
Thanks for your reaply and suggestion.  I really appreciate it!

Currently I only have the URL link that a API returns like this:

Here is a screen shot of the extension showing how the URL is automaticaly loaded into the extension to preview it when I click the "LoadModel" button. (it loads the THREE.GLTFLoader to preview the model within the extension)

I can coppy the link in a browser eg. chrome hit the return button and it downloads a .glb file to my computer.
I can then inport that file into AE like this

What I'm looking to do is when I click the "downloadFile" button the long URL link from the API is downloaded to my computer, then use the "importToAE" button to load that .glb file into AE.
Idealy I would want the "importToAE" button to do the downloading part before the import, thus saving a botton click.
But was thinking it would be to comnplicated for javascript to handle.

Anyone have any suggestions on how to do this? 
Thank you in advance!
