Support for Lamda function URL

Is work underway to support Lambda function URLs as mentioned in https://docs.aws.amazon.com/lambda/latest/dg/lambda-urls.html? Could custom mapper be used to get this to work?

Start with the AWS Lambda function URLs documentation linked in the issue, then inspect the repository's custom mapper and request-handling entry points. Determine the Lambda Function URL event and response requirements; done means the project supports those requests with documented behavior and tests.
