const Folder = <Params extends Parameters<typeof Config.all>[0]>(name: string, arg: Params) => Config.nested(Config.all(arg), `${name}`);

export const EnvironmentVariables = Config.all({
    axiom: Folder("AXIOM", {
        token: Config.redacted("TOKEN"),
        datasetName: Config.string("DATASET_NAME"),
    }),
        ...
});

Config.nested(Config.all(arg), `${name}`);

Config.nested(Config.all(arg), `${name}_`);
