[keycloak-user] Group user property for SAML client authentication

Hello Guys, I'm currently trying to set up a SAML authentication via Keycloak to pull the group attribute, I was wondering if anyone knows the keyword for the client user property to pull the group value? for example, to pull the email attribute, the keyword for the property box will be 'email', how about the group? apparently, it wasn't 'group' Any help is much appreciated
