// Generates a user attribute verification code for the specified attribute name.
// Sends a message to a user with a code that they must return in a
// VerifyUserAttribute request. This action might generate an SMS text message.
// Starting June 1, 2021, US telecom carriers require you to register an
// origination phone number before you can send SMS messages to US phone numbers.
// If you use SMS text messages in Amazon Cognito, you must register a phone number
// with Amazon Pinpoint (https://console.aws.amazon.com/pinpoint/home/) . Amazon
// Cognito uses the registered number automatically. Otherwise, Amazon Cognito
// users who must receive SMS messages might not be able to sign up, activate their
// accounts, or sign in. If you have never used SMS text messages with Amazon
// Cognito or any other Amazon Web Service, Amazon Simple Notification Service
// might place your account in the SMS sandbox. In sandbox mode (https://docs.aws.amazon.com/sns/latest/dg/sns-sms-sandbox.html)
// , you can send messages only to verified phone numbers. After you test your app
// while in the sandbox environment, you can move out of the sandbox and into
// production. For more information, see SMS message settings for Amazon Cognito
// user pools (https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-identity-pools-sms-userpool-settings.html)
// in the Amazon Cognito Developer Guide.

	// A map of custom key-value pairs that you can provide as input for any custom
	// workflows that this action triggers. You create custom workflows by assigning
	// Lambda functions to user pool triggers. When you use the
	// GetUserAttributeVerificationCode API action, Amazon Cognito invokes the function
	// that is assigned to the custom message trigger. When Amazon Cognito invokes this
	// function, it passes a JSON payload, which the function receives as input. This
	// payload contains a clientMetadata attribute, which provides the data that you
	// assigned to the ClientMetadata parameter in your
	// GetUserAttributeVerificationCode request. In your function code in Lambda, you
	// can process the clientMetadata value to enhance your workflow for your specific
	// needs. For more information, see Customizing user pool Workflows with Lambda
	// Triggers (https://docs.aws.amazon.com/cognito/latest/developerguide/cognito-user-identity-pools-working-with-aws-lambda-triggers.html)
	// in the Amazon Cognito Developer Guide. When you use the ClientMetadata
	// parameter, remember that Amazon Cognito won't do the following:
	//   - Store the ClientMetadata value. This data is available only to Lambda
	//   triggers that are assigned to a user pool to support custom workflows. If your
	//   user pool configuration doesn't include triggers, the ClientMetadata parameter
	//   serves no purpose.
	//   - Validate the ClientMetadata value.
	//   - Encrypt the ClientMetadata value. Don't use Amazon Cognito to provide
	//   sensitive information.
