Monitoring multiple ElasticSearch Clusters for single kibana

Hi,

In a scenario, I have 2 different clusters. Each clusters has 2 masters and 3 data nodes with 7.x Elastic version.

How to I using single kibana to monitor this multiple clusters?

Thanks,
Ecem

The only option I know of is cross cluster search, but that requires connections between the clusters.
