Authentication Required to save a file to Creative Cloud on IOS IPhone Mobile Chrome App

 I am trying to save my pdf downloads from safari and chrome directly into my creative cloud, but it will not let me save them because it's not authenticated, but when I click the link it just opens the app. How do I make it possible to save a pdf using the print option in chrome? Can I use creative cloud options in chrome using the print feature? Do I have to save a pdf of invoices a different way? 

thank you all so much.
