    This sample retrieves the user's profile photo, uploads it to OneDrive,
    creates a view-only sharing link for the photo, and sends an email
    with the photo attached.

    The code in this function includes many print statements to provide
    information about which endpoints are being called and the status and
    size of Microsoft Graph responses. This information is helpful for
    understanding how the sample works with Graph, but would not be included
    in a typical production application.
