# `aws-account-alternate-contact-with-terraform/management_account`

## Description

This Terraform module implements an AWS IAM role and Amazon EventBridge rule attached to the account's default EventBridge event bus. The EventBridge rule consists of a cross-account event trigger that invokes the Lambda function in your delegated account when a new account is added to your AWS Organizations.
