Send HTTPclient post request but dont wait for response and subscribe when backend call sends response back

问题

I am new to Angular and RxJS operators. I need help in one of the scenario in which I upload multiple documents at once in the backend (Rest API).

Processing the documents takes time in backend my my observable gets timeout in 2 minutes.

Now I am thinking of the solution in which I will send the post request to backend and will not wait for the response. And subscribe whenever response is ready by backend.

Please suggest if my approach is ok ? and how to achieve it in angular 8 with and Rxjs operators.

below is the my httpclient post method:

createNewVersion(formData: FormData) {
    let payload = new HttpParams();
    return this.httpClient
      .post(endpoint, formData, { params: payload }).subscribe((response: boolean) => {
        this.isLoading = false;
        if (response != null)
          this.observableVersion.next(true);
      });
  }

Currently I am facing timeout error after 2 minutes when response doesnt comes from backend that is why I have to change the logic.

Please help.
