// Some API operations in a user pool generate a challenge, like a prompt for an
// MFA code, for device authentication that bypasses MFA, or for a custom
// authentication challenge. A RespondToAuthChallenge API request provides the
// answer to that challenge, like a code or a secure remote password (SRP). The
// parameters of a response to an authentication challenge vary with the type of
// challenge. For more information about custom authentication challenges, see
// Custom authentication challenge Lambda triggers (https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-lambda-challenge.html)
// . Amazon Cognito doesn't evaluate Identity and Access Management (IAM) policies
// in requests for this API operation. For this operation, you can't use IAM
// credentials to authorize requests, and you can't grant IAM permissions in
// policies. For more information about authorization models in Amazon Cognito, see
// Using the Amazon Cognito native and OIDC APIs (https://docs.aws.amazon.com/cognito/latest/developerguide/user-pools-API-operations.html)
// . 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/user-pool-sms-settings.html)

	// 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 RespondToAuthChallenge
	// API action, Amazon Cognito invokes any functions that are assigned to the
	// following triggers: post authentication, pre token generation, define auth
	// challenge, create auth challenge, and verify auth challenge. When Amazon Cognito
	// invokes any of these functions, 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
	// RespondToAuthChallenge 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)

	// 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
