My managed package Apex code is making callouts but I can't use a packaged Named Credential as the user also needs to be able to adjust the endpoint URL not only the username and password.
I planned on using per-user named-credentials (with a predefined name or label) for that but now I am unable to query / find out. There is no User field on Named Credential that I can SOQL.
Who am I supposed to access it then?
