I'm going to install a node "node-red-node-email" additionally in node-red using Enviroment Variable instead of using npm " npm install node-red-node-email". I don't find the list of environment variable used for nod-red.
I'm looking for similar to grafana environment variables list in the below url: (https://grafana.com/docs/grafana/latest/installation/configuration/ )
Could you please me on this installation via Environment variable?
