// ### About this Flow ###
// Using Custom Auth Flow through Amazon Cognito User Pools with Lambda Triggers to complete a 'CUSTOM_CHALLENGE'. 
//
// ### About this function ###
// This CreateAuthChallengeSMS function (2nd of 4 triggers) creates the type of 'CUSTOM_CHALLENGE' as a one-time pass code sent via SMS. A one-time randomly generated 6-digit code (passCode)
// is sent via SMS (through Amazon SNS) to the user's mobile phone number during authentication. The generated passCode is stored in privateChallengeParameters.passCode and passed to the VerifyAuthChallenge function
// that will verify the user's entered passCode (received via SMS) into the mobile/web app matches the passCode passed privately through privateChallengeParameters.passCode.

// ### Next steps ###
// Instead of using the "crypto-secure-random-digit" library to generate random 6-digit codes, create a base32 secret for the user (if not exist) and

// ### About this Flow ###
// Using Custom Auth Flow through Amazon Cognito User Pools with Lambda Triggers to complete a 'CUSTOM_CHALLENGE'. This is the same flow as one-time passcode generated and sent via SMS or Email. 
// Instead, the service and user share a secret that was created during registration and both generate a 6-digit code based on the shared secret. 
// If the two codes (typically only good for 30 seconds) match, the user is authenticated.
//
// ### About this function ###
// This DefineAuthChallengeCustom function (1st and 4th of 4 triggers) defines the type of challenge-response required for authentication. 
// For HOTP, TOTP, U2F, or WebAuthn flows, we'll always use 'CUSTOM_CHALLENGE' and this function code won't change between the various auth methods.
