AWS LAMBDA FUNCTION HANDLER FOR RABBITMQ -- RABBITMQEVENT

I would be grateful if shown  the RabbitMQEvent class object( nugget package) that can be used to develop AWS Lambda Function.
Refer to AWS Lambda now supports Amazon MQ for RabbitMQ as an event source. Just as we have for Amazon.Lambda.S3Events
