// Returns information about all grants in the Amazon Web Services account and
// Region that have the specified retiring principal. You can specify any principal
// in your Amazon Web Services account. The grants that are returned include grants
// for KMS keys in your Amazon Web Services account and other Amazon Web Services
// accounts. You might use this operation to determine which grants you may retire.
// To retire a grant, use the RetireGrant operation. For detailed information
// about grants, including grant terminology, see Grants in KMS (https://docs.aws.amazon.com/kms/latest/developerguide/grants.html)
// in the Key Management Service Developer Guide . For examples of working with
// grants in several programming languages, see Programming grants (https://docs.aws.amazon.com/kms/latest/developerguide/programming-grants.html)
// . Cross-account use: You must specify a principal in your Amazon Web Services
// account. However, this operation can return grants in any Amazon Web Services
// account. You do not need kms:ListRetirableGrants permission (or any other
// additional permission) in any Amazon Web Services account other than your own.
// Required permissions: kms:ListRetirableGrants (https://docs.aws.amazon.com/kms/latest/developerguide/kms-api-permissions-reference.html)
// (IAM policy) in your Amazon Web Services account. Related operations:
//   - CreateGrant
//   - ListGrants
