How to get header value in server response on Angular Http Client?

Question

Angular

The server, in addition to the data, responds with an additional data_count parameter in the headers How do I get this parameter when making a request?
I try like this but it doesn't work

this.http.post<any>('Server/api/',{}
    ).subscribe((res: Response) => {
      console.log(res.headers.get('data_count'));
}

By default, the request returns json.
Enter observe: "response" in the request options. Third argument
