Elastic Cloud Kibana with Single Sign On from Azure Active Directory

Ok thanks I am really just looking for setting up single sign on to Kibana. Are there limitations to having our clusters stood up in Azure vs. AWS for this setup. Have you successfully implemented this solutions with customers that use Azure Active Directory? This article references Azure Active Directory Premium as well which I'd like to confirm is needed, and wasn't sure if this was allowed to connect to the cloud instance.

Thanks!
