Dabar problema tame, kad jei sukuri useri su google, nesusikuria Company model, kaip galima butu iterpti sitoje funkcijoje ir company modelio susikurima kartu su useriu?

public function handleProviderCallback()
    {
        try {
            $user = Socialite::driver('google')->user();
        } catch (\Exception $e) {
            return redirect()->to('/')->with('error', 'Oops. Something went wrong.');
        }

        $existingUser = User::where('email', $user->getEmail())->first();

        if ($existingUser) {

            $existingUser->update([
                'full_name' => $user->getName(),
                'provider_id' => $user->getId(),
                'email' => $user->getEmail(),
                'email_verified_at' => Carbon::now(),
                'provider_name' => 'google'
            ]);

            auth()->login($existingUser, true);

        } else {
            $newUser                    = new User;
            $newUser->provider_name     = 'google';
            $newUser->provider_id       = $user->getId();
            $newUser->full_name         = $user->getName();
            $newUser->email             = $user->getEmail();
            $newUser->email_verified_at = now();
            $newUser->save();

            auth()->login($newUser, true);
        }
        return redirect($this->redirectPath());
    }
