  permission_sets = {
    AdministratorAccess = {
      description      = "Provides full access to AWS services and resources.",

      managed_policies = ["arn:aws:iam::aws:policy/AdministratorAccess"]
    },
  }
  account_assignments = [
    {
      principal_name = "management"
      principal_type = "GROUP"
      permission_set = "AdministratorAccess"
      account_ids    = ["123456789", "234567890"]
    },
  ]
}
