Adobe Scan importing pdf on ipad

Hello,

I am on an iPad Pro (14.0.1) using Adobe Scan (AS). I'm having a difficult time understanding how to import a PDF of a scan. I can't figure out how to get AS to access My Files on iPad — it only seems to be able to access Photos, a location I can't save PDFs to.

Am I missing something? I'm surprised that Acrobat and AS don't talk to each other on iPad (eg, an option for "Open in…"), or that AS doesn't talk to My Files (again, an option for "Open in…").

Thanks in advance 🙂
