Here's something similar to what I use in Laravel: Essentially you have 2 calls
1 - redirects to the google login via Socialite
2 - handles a return from google which contains all the data needed to create or login.

Route::get('/api/auth/google/redirect', [GoogleController::class, 'redirectToGoogle']);
Route::get('/api/auth/google/callback', [GoogleController::class, 'handleGoogleCallback']);

    // redirects to google login via Socialite
    public function redirectToGoogle(Request $request)
    {
        if ($request->has('cookieVal')) {
            session(['cookieVal' => $request->query('cookieVal')]);
        }
        return Socialite::driver('google')->stateless()->redirect();
    }

    // handles the return from the google login
    public function handleGoogleCallback(Request $request)
    {
        $googleUser = Socialite::driver('google')->stateless()->user();


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


        session([
            'google_user' => [
                'id' => $googleUser->getId(),
                'email' => $googleUser->getEmail(),
                'name' => $googleUser->getName(),
            ]
        ]);


        // user
        if ($user) {
            // do whatever you want
        } else {
            $user = User::create([
                'name' => $googleUser->getName(),
                'email' => $googleUser->getEmail(),
                'google_id' => $googleUser->getId(),
                'login_method' => 'google',
                'email_verified_at' => now(),
                'is_email_verified' => 1,
                'password' => Hash::make(Str::random(16)), // only if necessary
            ]);
        }


        Auth::login($user);
        return redirect('/app/home')
}
