[sdk][openstacksdk][keystone] Does openstacksdk support v3tokenlessauth?

Does openstacksdk support keystone auth type "v3tokenlessauth"? I got this error message when trying to enable openstacksdk with auth_type="v3tokenlessauth" openstack.exceptions.NotSupported: The identity service for TEST: exists but does not have any supported versions. The following are the possible relevant documents I could find, and there is no place mentioning the support for tokenless auth using openstacksdk: https://docs.openstack.org/openstacksdk/latest/user/config/configuration.htm... https://docs.openstack.org/keystone/train/admin/configure_tokenless_x509.htm...
