I have doubts on how to properly delete entries using Python Given this schema

definition user {  }

definition group {
    relation permission_sets: permission_set
}

definition permission_set {
    relation members: user

    relation group_subgroups_create: role:*
    permission can_group_subgroups_create = group_subgroups_create

    // many more relation/permission pairs
}

And these relationships

group:supergroup#permission_sets@permission_set:admin
permission_set:admin#members@user:tom

If I use

DeleteRelationships

method to remove

permisson_set:admin

, the

group:supergroup#permission_sets@permission_set:admin

isn't deleted?

spicedb_client.DeleteRelationships(DeleteRelationshipsRequest(
            relationship_filter=RelationshipFilter(
                resource_type="permission_set",
                optional_resource_id="admin",
            )
        )
)

From my integration tests, it looks like I need to explicitly delete the group relation

spicedb_client.DeleteRelationships(DeleteRelationshipsRequest(
            relationship_filter=RelationshipFilter(
                resource_type="group",
                resource_id="supergroup",
                relation_type="permission_sets",
                subject_type="permission_set",
                subject_id="admin",
            )
        )
)

Is this correct? Is there a way to cascade the delete of

permission_set:admin

so that every reference to "admin" is removed? Furthermore, it looks like order matters, and first I need to remove the relation

group:supergroup#permission_sets@permission_set:admin

, or deleting the permission_set does nothing.
