If the response issues an authorization challenge, OkHttp will ask the [`Authenticator`](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) (if one is configured) to satisfy the challenge. If the authenticator supplies a credential, the request is retried with that credential included.
