Replacement for ResponseContentType in Angular 8+?

In this question:

Angular 6 ResponseContentType

The Author imports ReponseContentType like this:

import { HttpClient, ResponseContentType } from '@angular/common/http';

Is there a replacement for this in Angular 8+ that we can use that supports the same use cases?

In this document it says that the closest replacement is HttpClient:

https://angular.io/guide/deprecations#http

But I don’t see the types available on the HttpClient.
