hi guys i'm working at installing datahub with some required service separately deployed using respective chart. but with elasticsearch i'am facing this error :

going to use protocol: http
going to use default elastic headers
not using any prefix

 datahub_analytics_enabled: true

>>> GET _ilm/policy/datahub_usage_event_policy response code is 000
>>> failed to GET _ilm/policy/datahub_usage_event_policy ! -> exiting

is there any guide on how to deploy datahub but using other chart to deploy required service instead of using the one that provided in datahub helm chart github? did i miss something like init script?
