Java/quarkus REST service deployed to AWS lambda without a request handler & integrated w/ API Gateway?

I have a java/quarkus application that is accessed via http/REST - the code uses jax-rs. I need to have it deployed as an AWS lambda integrated w/ an AWS API Gateway.

Do I need to write a lambda RequestHandler (e.g. accepting a APIGatewayProxyRequestEvent) in my java code? Or is there a way to have my java/quarkus deployed to AWS as a lambda and tell API Gateway to make the http/REST requests to my application? IOW, I want to avoid adding the lambda requesthandler and just have a REST service.
