How to use private en vars in payload.config.ts ?

[franckmartin]

Hi,

We're using dotenv to manage our environment variables. But in order to access them from payload.config.ts they need to be prefixed with PAYLOAD_PUBLIC which is kind of a problem for private variables (e.g. S3_SECRET_KEY required by the plugin-cloud-storage/s3). What is the proper way to import environment variables in payload configuration without resorting to public variables ?
