How to implement an after doc saved callback or chain a promise after a resolver?

Hi, I need to implement an after-doc-saved callback or to chain a promise after a mutation resolver in order to add later subscriptions. How can I implement that? Using .wrapResolve() maybe but how should I do it properly? Thanks.

const middleware = next => async rp => {
  // before mutation logic
  // somehow change `rp`

  const payload = await next(rp);

  // after mutation logic change `payload`
  // eg. payload.record will contain mongoose document
 
  return payload;
}

schemaComposer.Mutation.addFields({
    userCreate: UserTC
      .getResolver('createOne')
      .wrapResolve(middleware),
});

This makes a lot of sense. Thought on awaiting but didn't know if it was the proper way. Thanks @nodkz ! I'll try it this way.
