Downloadable link from public box link

I'd like to be able to retrieve a pdf from a public Box link through python, but I'm not quite sure how I can do this. Here's an example of the type of pdf I hope to be able to download: https://fnn.app.box.com/s/ho73v0idqauzda1r477kj8g8okh72lje

I can click the download button or click a button to get a printable link on my browser, but I haven't been able to find the link to this page in the source html. Is there a way to find this link programmatically? Perhaps through selenium or requests or even through the box API?

Thanks a lot for the help!
