using middleware in "non-graphql-yoga" server

[DnSu]

I'm using apollo-server-lambda with @graphql-tools/schema. I can't seem to figure out how to apply the middleware to a specific resolver. I tried to put it in ApolloSever({ middleware }) (per this article), but that seems to only work on graphql-yoga

const beepMiddleware = async (resolve, root, args, context, info) => {
  console.log('before beep');
  context.beep = true;
  const result = await resolve(root, args, context, info);
  console.log('after beep');
  return result;
};

const schema = makeExecutableSchema({
  typeDefs: [
    helloType,
  ],
  resolvers: [
    helloResolver,
  ],
});

const server = new ApolloServer({
  schema,
  introspection: true,
  plugins: [ApolloServerPluginLandingPageGraphQLPlayground()],
});

export const handler = server.createHandler();
