NextCloud 13 SAML 'password required'

I’m using NextCloud 13 with user_saml. I got my personal SAML user into the admin group so I can do admin tasks. I’m attempting to connect my personal files to this user, and when making a 1 time password at Settings->Security->Create a new app password, I get a ‘password required’ popup. I can’t get past this screen.

How do I preform administrative tasks with a SAML user if that user doesn’t have a real ‘password’ associated?
