A rookie proposes SAML user attribute mapping

[biliblihuorong]

I'm trying to configure SAML and I'm finding that the CF test results in nothing.

I tried clicking on the preview, but it didn't let me see some fields unlike OIDC.

I then tried to create a new Property Mappings but I looked up the documentation and I don't know how to get the user's group and the user's nickname username variable name, I read the documentation but I didn't find the appropriate values, I configured a variable for email and it works fine though.
