We don't have direct support to load the document
from Azure storage/private URL. However, we can achieve it in the sample by
retrieving the document as a stream from Azure storage or a private URL before
loading it into the PDF Viewer. Once we get the document as stream then we can
load it into our PDF Viewer control.
Kindly find the documentation
below for loading the stream.
