but the LookupSubjects response can't get the permission resource.

[{"subjectObjectId":"X3TFQYRE3779","excludedSubjectIds":[],"permissionship":1,"excludedSubjects":[],"lookedUpAt":{"token":"GhUKEzE3MTgxNTkzMTUwMDAwMDAwMDA="},"subject":{"subjectObjectId":"X3TFQYRE3779","permissionship":1}},{"subjectObjectId":"EDVDLT8KHQML","excludedSubjectIds":[],"permissionship":1,"excludedSubjects":[],"lookedUpAt":{"token":"GhUKEzE3MTgxNTkzMTUwMDAwMDAwMDA="},"subject":{"subjectObjectId":"EDVDLT8KHQML","permissionship":1}}]

I can't build the message like user1 is resource2:viewer.
