How to get the ID of the current open product category in Bitrix?

Question

1C-Bitrix

I want to display subcategories for each product category.

I do it like this:

$APPLICATION->IncludeComponent(
  "bitrix:catalog.section.list", 
  "template1", 
  array(
    "ADD_SECTIONS_CHAIN" => "Y",
    "CACHE_FILTER" => "N",
    "CACHE_GROUPS" => "Y",
    "CACHE_TIME" => "36000000",
    "CACHE_TYPE" => "A",
    "COMPONENT_TEMPLATE" => "template1",
    "COUNT_ELEMENTS" => "Y",
    "FILTER_NAME" => "sectionsFilter",
    "HIDE_SECTION_NAME" => "N",
    "IBLOCK_ID" => "4",
    "IBLOCK_TYPE" => "catalog",
    "SECTION_CODE" => $_REQUEST["SECTION_CODE"],
    "SECTION_FIELDS" => array(
      0 => "NAME",
      1 => "PICTURE",
      2 => "",
    ),
    "SECTION_ID" => ,
    "SECTION_URL" => "/catalog/#SECTION_CODE#/",
    "SECTION_USER_FIELDS" => array(
      0 => "",
      1 => "",
    ),
    "SHOW_PARENT_NAME" => "Y",
    "TOP_DEPTH" => "3",
    "VIEW_MODE" => "TILE"
  ),
  false
); */

And everything is OK, it remains only to insert the desired ID in the "SECTION_ID" field
Tried like this:

$rsSections = CIBlockSection::GetList(array(),array('IBLOCK_ID' => $arParams ['IBLOCK_ID'], '=CODE' => $arResult['VARIABLES']['SECTION_CODE']));
$arSection = $rsSections->Fetch();

But for some reason the same ID is issued in any section. And the partition structure itself, even in breadcrumbs, begins to appear as if the entire directory lies in the section whose ID is displayed.

What's wrong? Is there a simple solution to my problem?

I see a complex component of the catalog there, you can get this value $arResult['VARIABLES']['SECTION_CODE'] in the template files of the complex component.
