How to access Elastisearch domain URL?

Question

I have created elasticsearch domain in AWS and integrated with cloudwatch logs which eventually sends logs to elasticsearch cluster with help of lambda function. It has got successfully created and it gives me one endpoint URL, something like this `https://search-elkprod-c63hwtlyqgdogkw55w6osdfzwu.eu-west-1.es.amazonaws.com'.

When i click this link i get this message :

{
  "name" : "S7hluCW",
  "cluster_name" : "567294256180:elkprod",
  "cluster_uuid" : "4UdCvJT9R4-H05MSXqg9tQ",
  "version" : {
    "number" : "6.5.4",
    "build_flavor" : "oss",
    "build_type" : "zip",
    "build_hash" : "d2ef93d",
    "build_date" : "2019-04-08T13:15:27.206923Z",
    "build_snapshot" : false,
    "lucene_version" : "7.5.0",
    "minimum_wire_compatibility_version" : "5.6.0",
    "minimum_index_compatibility_version" : "5.0.0"
  },
  "tagline" : "You Know, for Search"
}

Now my questions are:

1. How to access this cluster? I want to check whether my logs are going to the cluster or not.
2. If this is a cluster, where are the instances that would have been launched with this cluster?

Please help me on this. Please let me know if you need any more clarification.
