Is it possible to use WebShare API (navigator.share) to share images from other origins than my own?

I’m trying to use the file field of navigator.share in order to share an X amount of images which can come from other origins/urls than my own website, but the files field expects File objects, which I’m currently getting through the fetch function and then using .blob() on the response result.

The problem is that unlike using tags with the src attribute I can’t use fetch to pull images from other origins which is a functionality that I need to finish my product.

I tried to pull the images using fetch which is constrainted by CORS, that means I can’t use .share to share any image I want but only those that are from my origin.
