[ELASTIC CLOUD] Create Index to Keep Track of Kibana User Logins

This is most likely a redundant question but I have failed to find the answer that I am looking for.

Background:
I have an Elastic Cloud cluster with the platinum subscription.

Desired Result:
Understand how to create an index comprised of Kibana User logins and the associated IP address. This may not even be possible but I have spent 3 hours going through the EC documentation as well as various discussion posts.

Any help at all would be greatly appreciated!

This is not currently possible unfortunately.
