Hi all, we are just starting to implement some permissions with spicedb, the docs and the google groups example helped us a lot. We were wondering if you could give us some feedback on what we have so far. The specific permissions and entities of our schema in the playground: https://play.authzed.com/s/PAdE2Y8GYMEN/schema Our main question is what is the best way of implement global permissions? So far, we have a root resource (platform in the playground) that need to be referenced every time we need to use global permissions, is that the correct approach?
