To receive the push notification in the background , need to init firebase sdk in the background using service worker as per this doc

here when the Firebase config is added statically everything is working fine .

In service worker, process.env.ENV_NAME is not available, how to init SDK in server worker which allows to inject firebase config dynamically in Next Js via environment variable?
