How can I get deprecated warnings in GraphQL query response

I need to get deprecated warnings in GraphQL query response as in the below image (inside extensions):

enter image description here

Currently, once I added @deprecated to the Type definition, I do not get the "extensions" parameter in the response.

type Post {
    title: String
    isPublished: Boolean @deprecated(reason: "no longer supported")
}

How I can achieve this with NodeJS apollo-server
