You can also just directly reference the session properties, to avoid the overhead of the function call.

It depends on _which_ scripting area you're using, because the availability of arguments dictates the source your reference, but for most scripts you'd reference `self.session.props.auth.user.userName` (assuming a source of `self`). Inside of expressions you'd use `{this.session.props.auth.user.userName}`.
