How to limit google maps autcomplete search to only european countries in php?

I am trying to get autocomplete list based on input with google maps api in php. I want to get only results from Europe. I tried using ‘components’ => ‘country:de’ filter but that gets only one to five countries and I need more. Any help is appreciated. Here is my code.

php class

<?php

namespace AppSupport;

use GuzzleHttpClient;
use IlluminateSupportFacadesDB;
use SymfonyComponentHttpFoundationJsonResponse;
use SymfonyComponentHttpFoundationResponse;

class AutocompleteHandler
{
    public const BASE_URL = "https://maps.googleapis.com/maps/api/place";
    private $key;

    public function __construct()
    {
        $this->key = config('services.googlekey.key');
    }

    public function placeId(string $address): JsonResponse
    {
        $url = sprintf(
        '%s/autocomplete/json?%s',
         self::BASE_URL,
         http_build_query([
        'input' => $address,
         'types' => '(cities)',
         'components' => 'country:de',
         'key' => $this->key,
         ]));

        try {
            $client = new Client();
            $response = $client->request('get', $url);
            $responseJson = $response->getBody()->getContents();
            $responseArray = json_decode($responseJson, true);

            return response()->json(collect($responseArray['predictions'])->map(
                function ($value) {
                    return [
                        'id' => $value['place_id'],
                        'label' => $value['description'],
                    ];
                }
            ));
        } catch (Exception $e) {
            return response()->json([
                'error' => $e->getMessage(),
            ], Response::HTTP_INTERNAL_SERVER_ERROR);
        }
    }
}
