View books on Digital Editions app on iOS?

Hi everyone, I am not an expert on these topics at all, so forgive my ignorance on this matter.

I downloaded books for school on Adobe Digital Editions 4.5 on my Mac. I wanted to know how can I view them on my iOS mobile device? I already downloaded the Digital Editions app on my phone. I authorized my account on the app, but cannot view my books in there.

Again, sorry for the lack of knowledge on this, and for my English.

Thank you!

Anna
