Admin config: Optional sso master password policy

Hello everyone! I would like to know how to configure this field that appears on the admin page of Vaultwarden. This version of Vaultwarden comes from Timshel’s repository, where it has SSO-enabled and SSO-support. I understand that the SSO_MASTER_PASSWORD_POLICY field configures the master password, but I’m not sure how it should be set up, or if it’s possible to configure it so that users don’t need to enter the master password, allowing access only through SSO.

Thank you very much; I look forward to your response!
