Setting up an SSL certificate for Neo4J via AWS

Suppose I want to access my Neo4J DB via a webaddress such as:

https://neo4j.mysite.com:7473

In order for that to work, SSL certificates need to be set up via the configuration in Neo4J itself.

There is an instruction on Medium by Neo4J which explains how to set this up here: https://medium.com/neo4j/getting-certificates-for-neo4j-with-letsencrypt-a8d05c415bbd

However, what if I want to use, let's say, AWS certificates? For example, what if I set a load balancer on neo4j.mysite.com which will be listening on the port 7473 and then simply redirect it to the right IP address internally? How do I set the Neo4J config file in this case? There's no documentation on that...

Thank you!
