Upload Images using presigned url

Hey,

I’m wondering if that is possible to upload an image directly from a front-end app having some sort of “presigned url” as same as AWS S3. So far the only way I can find in docs is basically by uploading the image to a service that controls authorization. I know it works, but I’m working if I can save resources. The closest stuff I could find is this Embargoed assets, but it doesn’t seem to work for upload.

Thanks!
