@machadoum @jaredburgettelastic, is there a test environment you could share for this feature? https://kibana.siem.estc.dev/ was EOLed at the end of last year.

I was able to access the feature here:
https://edge-sec.kb.us-west2.gcp.elastic-cloud.com/app/security/entity_analytics_entity_store

The env is: [edge-sec](https://edge-sec.kb.us-west2.gcp.elastic-cloud.com/): it runs the latest unstable version actually able to run a stack ([docs](https://studious-disco-k66oojq.pages.github.io/edge-sec))
