Allow user identification without ssoToken (again)

As I understand it, I should be able to identify my logged-in users without an ssoToken: [https://quackback.io/docs/widget/identify-users#identify-logged-in-users](https://quackback.io/docs/widget/identify-users#identify-logged-in-users) Nevertheless, identification fails with an validation error, stating the required ssoToken was missing.
