accessing context values in field resolver

[chattling]

I am trying to implement custom directive as in this example: https://www.graphql-tools.com/docs/schema-directives#enforcing-access-permissions

In example the function getUser used to retrieve user details (roles) based on token sent in auth header.
But what if I already retrieved the user previously and pushed it into context like so:

const server = new ApolloServer({
schema,
csrfPrevention: true,
cache: 'bounded',
context: async ({ req }) => ({ req, pubsub, authUser: await getAuthUser(req.headers.authorization), dataLoaders: dataLoadersGenerator() }),
...

It is available in Query/Mutation resolvers on context object.
I would like not to do the user retrieval again from database.
How can I retrieve authUser object from context in field resolver in example above?

I found answer myself. When I console.log'ed the "context" object my custom authUser object was not printed, so I assumed it is not there. But when I analyzed context object via debugger, it was actually present there. So this is already working as I expected and I can access it via "context.authUser" inside custom field resolver function.
