Looking for TCP Relay functionality like ngrok in the AWS

Question

I have a website running on AWS Ec2 instance and  want to expose it to a public endpoint without opening any port on the ec2 instance. How to hook some cloud resource or the application in front of my website so that it can be accessed by someone in public internet? What I need is that a tcp relay functionality-a call from public internet browser is routed to my local website on ec2 with minimal effort. If AWS doesn’t expose such a relay functionality, can something be done using web sockets in AWS-iot? I found ngrok as a 3rd party tool and I want to stick to AWS only.

This is what a CLB in AWS does. The load-balancer is globally-accessible which forwards the traffic to the instance. And nobody connects directly to the instance. Of course, you need to open a port on instance for load-balancer to access it, but you have to do that with any relay solution.
