GraphQL Playground: I can't access Schema and Docs in Production

After some debugging in chrome debugging tools. I found out that introspection config need to be put in apolloServer.

Something like this:

module.exports = ({ env }) => ({
  graphql: {
    config: {
      playgroundAlways: env.bool("ENABLE_GRAPHQL_PLAYGROUND", false),
      apolloServer: {
        tracing: false,
        introspection: env.bool("ENABLE_GRAPHQL_PLAYGROUND", false),
      },
    },
  },
});
