I have problem with CORS error. I do request for Google oAuth2 and i get a CORS ERROR: I want to get google authentication and generate a JWT token. When I do it without using the client everything is fine. When I send angular requests this is a problem with CORS. I allow all types of CORS. Why am I getting this error?

My Angular request:
googleLogin(): Observable<LoginResponse> {
return this.http.get<LoginResponse>

.pipe(tap(response => {
localStorage.setItem('access_token', response.accessToken);
}));
}
//...
public onGoogleLogin(): void {
this.authService.googleLogin().subscribe();
}
//...
