    a: ['allowedUserId1'],  // Whitelisted user ids
    b: ['blockedUserId1'],  // Blacklisted user ids
  },
  
  'sessionUserId',          // Optional user id.
                            // If provided, authenticated user level will be assigned.
                            // Also, it will be tested against whitelist and blacklist ids.
                            // If not provided, user permission level will be 0.
                            
  3                         // Optional user level.
                            // If provided, this value will be used as the user's permission level.
