docs: <p>
  Adds or updates the policy that is specified as the IAM role's permissions boundary. You can use an AWS managed
  policy or a customer managed policy to set the boundary for a role. Use the boundary to control the maximum
  permissions that the role can have. Setting a permissions boundary is an advanced feature that can affect the
  permissions for the role.
  </p>
  <p>
  You cannot set the boundary for a service-linked role.
  </p>
  <important>
  <p>
  Policies used as permissions boundaries do not provide permissions. You must also attach a permissions policy to
  the role. To learn how the effective permissions for a role are evaluated, see <a
  href="https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_policies_evaluation-logic.html">IAM JSON Policy
  Evaluation Logic</a> in the IAM User Guide.
