Thank you! There it is:

<?php

use GuzzleHttp\Client;
use Pipedrive\versions\v2\Api\PersonsApi;

class Test 
{
    private const API_KEY_IDENTIFIER = 'x-api-token';

    public function test()
    {
        $id = 42;
        $configV2 = (new ConfigurationV2())->setApiKey(
            self::API_KEY_IDENTIFIER,
            'xxxxxxx'
        );

        $client = new Client();
        $personsApi = new PersonsApi($client, $configV2);

        $personsApi->getPerson($id);
    }
}
