Add Image By AWS S3 Presign Url

I am using aws s3 to store my images. I am adding image to diagram by specifying the public path. For security reasons, I need to make the images private and the only way to access it is by pre-signed url. My question is, do GOJS have a way to add image on diagram by this?

Isn’t that just a URL?

Internally the Picture.source value is just passed on as the src of an HTMLImageElement.
