Thanks @djjuhasz!

I noted the option to exclude attributes at the bottom of the issue description but never got to implement it. The attributes included in this PR are just examples and for testing purposes, they are based on a list provided by Dan (see the Keycloack configuration), I just removed the storage attributes to simplify.
