Create an EventBridge rule that triggers a Step Functions workflow
This pattern creates an EventBridge event bus and a Step Functions workflow. An EventBridge rules invokes the Step Functions target when a StartReminder event is published to the event bus.
Step Functions waits until the specified date before publishing a reminder event to the even bus using a Lambda function.
This pattern creates an IAM Role for the Lambda function that gives it permission to send to an EventBridge event bus that is created as part of the template.
Step Functions is also given permission to subscribe to EventBridge events on the newly created event bus.
