	// create the content of the approval rule, you can specify approvers in an
	// approval pool in one of two ways:
	//   - CodeCommitApprovers: This option only requires an AWS account and a
	//   resource. It can be used for both IAM users and federated access users whose
	//   name matches the provided resource name. This is a very powerful option that
	//   offers a great deal of flexibility. For example, if you specify the AWS account
	//   123456789012 and Mary_Major, all of the following would be counted as approvals
	//   coming from that user:
	//   - An IAM user in the account (arn:aws:iam::123456789012:user/Mary_Major)
	//   - A federated user identified in IAM as Mary_Major
	//   (arn:aws:sts::123456789012:federated-user/Mary_Major) This option does not
	//   recognize an active session of someone assuming the role of CodeCommitReview
	//   with a role session name of Mary_Major
	//   (arn:aws:sts::123456789012:assumed-role/CodeCommitReview/Mary_Major) unless you
	//   include a wildcard (*Mary_Major).
	//   - Fully qualified ARN: This option allows you to specify the fully qualified
	//   Amazon Resource Name (ARN) of the IAM user or role.
	// For more information about IAM ARNs, wildcards, and formats, see IAM Identifiers (https://docs.aws.amazon.com/IAM/latest/UserGuide/reference_identifiers.html)
