Hi, I'm working on the permission control of my project (golang). there are multiple

group

of `user`s, which contain `superUser`s coming from two sources: developers and externalSuperUser I have want to set different logics when displaying the user list under a group. That is, only superusers can see one another. my

schema.spicedb

is defined as following:

definiton group {
  relation member: user
  relation superUser: developerGroup:* | externalSuperUserGroup
}

definition developerGroup {
  relation member: user
}

definition externalSuperUserGroup {
  relation member: user
}

here's the main problem, after I got the original user list of a specific

group

, how can I filter out those who are belong to

superUser

relationship? I tried using LookupSubjects with param

resourceObjectType='group', subjectType='user', relation='superuser'

to find those who is superUser, but I got nothing from the query result. I think it's because the LookupSubjects can only query direct relationships. But I can't changes the structure of the schema here. Is there any way to find such indirect relationship? (find the

user

in

developerGroup

as a

superUser

in the

group

)
