Connect Kobo from Digital Editions iPad app

I wanted to connect my Kobo eReader to the Adobe Digital Editions to be able to load ebooks - however the instructions given don’t seem to work with the app. I have a usb C to USB adapter to be able to connect the Kobo to my iPad Pro. The Kobo is recognized when I go to the iPad Files app, but not in the ADE app. Am I missing something or is the app not going to recognize the Kobo?
