Enabling persistence in Mattermost manifest file

Troubleshooting
1

In the values.yml file for the Mattermost Team Edition Helm chart it has configuration for persistence like:

persistence:
  data:
      enabled: true
      size: 10Gi
      accessMode: ReadWriteOnce
  plugins:
      enabled: true
      size: 1Gi
      accessMode: ReadWriteOnce

So with this configuration Longhorn that we’ve deployed will automatically create a file storage. Is this also possible in the Mattermost manifest when I’m using the Mattermost Operator. I don’t see any documentation about this, only focused on external file storage like a S3 bucket. I just need to enable persistence without giving a URL and secret.

I tried to deploy the manifest, but I’m getting errors in the Mattermost Operator that it fails to check Minio instance.
