Use the callbackQuery method, something like this:

require_once "vendor/autoload.php";

try {
    $bot = new \TelegramBot\Api\Client('YOUR_BOT_API_TOKEN');
    // or initialize with botan.io tracker api key
    // $bot = new \TelegramBot\Api\Client('YOUR_BOT_API_TOKEN', 'YOUR_BOTAN_TRACKER_API_KEY');
    

    $bot->callbackQuery(function ($callbackQuery) use ($bot) {

    switch ($callbackQuery->getData()){
        case 'help':
            $message = 'Help is here!';
        break;
        default:
            $message = 'Hello!';
    }

    $bot->sendMessage($callbackQuery->getMessage()->getChat()->getId(), $message);

    });
    
    $bot->run();

} catch (\TelegramBot\Api\Exception $e) {
    $e->getMessage();
}
