Please, Increase Angular HTTPClient timeout

Here is my code. http is HTTPClient object in angular/common/http module.

extractMainContentFromServer(payload): Promise<any> {
        this.isLoadingSubject.next(true);
        return this.http.post<any>(
            `${API_DAEMON_URL}/daemons/extractMainContent`,
            payload,
            {
                headers: KTUtil.getAPIHeaders()
            }
        ).pipe(
            catchError( err => {
                if (err && err.error.message == 'RUNNING NIGHTMARE') {
                    this.toastService.show('Server is running, please 
                    edit later');
                }
                
                return of(undefined);
            }),
            finalize(() => this.isLoadingSubject.next(false))
        ).toPromise();
}

I done extensive research on Internet, seems no way with angular httpclient. It just keeps rerequesting after 60s. I don't want this timeout. Could be there possibly other way to post request with unlimited timeout? Thank you so much in advance.
