Need to setup cluster using operator having predefined database and user access to the database

We want to deploy the cockroach db cluster in k8s using operator. We need to have predefined database other than default one and user with password having access to the predefined database. What is the way to configure in operator. I can see helm chart is providing by executing k8s job. But I do not find configuration to do in operator.

Start by reviewing the operator configuration model and the Helm chart's Kubernetes Job path mentioned in the issue. Determine how predefined databases and users are expected to be configured, then verify the result against a Kubernetes deployment; done means a supported, reproducible configuration path is documented or implemented.
