How to get a list of coupons in Bitrix?

Question

1C-Bitrix

There is a list of coupons.

I can change them, by code or by ID

use Bitrix\Sale\Internals;

if (CModule::IncludeModule("catalog") && CModule::IncludeModule("sale")) {
   // $fields["DISCOUNT_ID"] = 8;
   $fields["COUPON"] = 'asd';
    // $fields["ACTIVE"] = "Y";
    // $fields["TYPE"] = 2;
    // $fields["MAX_USE"] = 0;
    $fields['DESCRIPTION'] = '111';
    $id = 4090104;

    $dd = \Bitrix\Sale\Internals\DiscountCouponTable::update($id, $fields); //Создаем купон для этого правила
    if (!$dd->isSuccess()) {
        $err = $dd->getErrorMessages();
    } else {
        echo 'Купон на скидку';
    }
}

How to get a list of coupons with data about them?

UPD found such a code, but it displays only 1 coupon, and do not set it as a list as a filter

use \Bitrix\Main,
    \Bitrix\Sale\Internals;

try
{
    /* @var string Номер купона */
    $code = 'asd';

    if ( !Main\Loader::IncludeModule('sale') )
    {
        throw new \Exception("Module 'sale' not installed");
    }

    $arCoupon = Internals\DiscountCouponTable::getRow([
        'filter' => [
            //'>ID' => 4090098,
            //'<ID' => 4090106,
            'COUPON' => 'asd',
        ]
    ]);

    if ( !empty($arCoupon) )
    {
        echo "<pre style='display: block !important;'>";
        print_r($arCoupon);
        echo "</pre>";
    }
    else
    {
        throw new \Exception("Coupon [CODE:{$code}] not found");
    }
}
catch( \Exception $e)
{
    var_dump($e->getMessage() );
}
