NOTE: This API is intended for internal use in ARM deployments. Users should use the data-plane REST service for interaction with vault secrets.

What exactly does this mean? I would like to use azure keyvault secrets in dbforpostgresql deployments for the admin password, meaning the password is stored in azure keyvault, and I know the name of the keyvault and the secret. Is there a better way to use it?
