mongo Custom Tracker store

[iasbm]

Hello,
can i request how to configure custom Tracker store ( we use Mongo DB) in Rasa helm chart

Before HELM, we have configured our custom tracker store in endpoints.yaml as follows

tracker_store: type: myTracker.MongoTrackerStore url: mongodb+srv://mongodb-URL db: admin username: admin password: mypassword

But not sure how can we make use of our custom tracker store when we deploy using K8S

We did give a try by configuring endpoints.trackerstore in values.yaml, but as per the comment i think it needs to enable postgresql.install = true, but we want to use MongoDB.

any suggestions pls?
