In Angular 9 - How to fetch a JSONP that doesn't have a callback function?

I'm trying to fetch de data the URL below:

http://storage.googleapis.com/nacleanopenworldprodshards/Nations_cleanopenworldprodeu1.json

I'm using Angular 9, and this is my service.ts:

import { Injectable } from '@angular/core';
import { HttpClient } from '@angular/common/http';



@Injectable({
  providedIn: 'root'
})
export class NationsService {

  constructor(private http: HttpClient) { }

  getData() {
    const url = 'http://storage.googleapis.com/nacleanopenworldprodshards/Nations_cleanopenworldprodeu1.json';

    return this.http.jsonp(url, 'callback');
  }

}

Simple enough, right? but it doesn't work. Because the "API" doesn't have a callback function. I searched a lot in stackoverflow but I did not find how to solve this.

Does anybody knows of a way to get the data using Angular 9?

Thanks you very much!
