How Do You Actually Use a Configuration Endpoint to Discover All Nodes in a Memcache Cluster?

[StevenXL]

According to this doc:

https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/AutoDiscovery.HowAutoDiscoveryWorks.html

It should be possible to use the Configuration Endpoint to do "service discovery" - i.e., discover all nodes within a cluster.

I don't see that being done here. Is this actually a thing that the configuration endpoint can be used for? If so, can someone point me to what calls are being made against that endpoint in order to discover the nodes?
