Kibana Multi-Tenancy

Its mentioned in one of the document (https://opendistro.github.io/for-elasticsearch-docs/docs/security/access-control/multi-tenancy/) that to support multi-tenancy opendistro creates a index for every tenant. Is this understanding is still true/correct?

I am asking this because i don’t see any additional .kibana_ index created as per the documentation.(Used GET /_cat/indices?v).

We are using AWS ElasticSearchService version 7.7 which uses opendistro for fine grained access control.

This understanding is crucial for our future implementation because having one index per tenant is not an option for us as we have huge tenant base
