Hi! I'm new to ReBAC and spicDB as well so i might not be getting all the concepts yet 😅 But i have a question: Given the following schema

yaml
definition user {}

definition group {
    relation member: user
}

definition prompt {
    relation creator: user
    relation editor: user
    relation viewer: user | group#member
    permission can_view = creator + editor + viewer
    permission can_edit = creator + editor
}

i'm trying to use the node js client to get a list of all the users who has the

can_view

permission and i am trying to do it like so:

typescript
    spicedbClient.lookupSubjects({
      resource: {
        objectId: promptId,
        objectType: 'prompt',
      },
      permission: 'can_view',
      subjectObjectType: 'user',
      optionalSubjectRelation: '', // the name suggests its optional but the ts types says otherwise.
      wildcardOption: v1.LookupSubjectsRequest_WildcardOption.EXCLUDE_WILDCARDS,
      optionalConcreteLimit: 0, // same here and passing anything else than 0 gives me a runtime error saying that the feature is not supported
    })

but i don't think this works as i am expecting it to as i get an empty array when i would expect an array with the creator which i set as follows:
