Installing operators as dependencies

I’ve got a Helm-based install process and would like to add a couple of operator installations (ex: KubeRay) as a part of my kots install process. Specifically, I need for KubeRay, etc to be installed prior to starting the install of my Helm chart.

How could I specify this sort of behavior in my configuration?

Potentially related: would enabling Longhorn for my application work similarly?

Update - this was due to an issue in my Helm chart, unrelated to Replicated! The issue is resolved.
