lastSuccessfulLoginDate property missing in Rest API /admin/v1/Users endpoint

I am trying to follow this Oracle article however when I am making the call to /admin/v1/Users endpoint the response does not contain the lastSuccessfulLoginDate property.

All I see is

"urn:ietf:params:scim:schemas:oracle:idcs:extension:user:User": {

        "isFederatedUser": true

    },
