How to display elements of a certain section of an infoblock on Bitrix?

Question

1C-Bitrix

Guys, tell me how you can display the elements of a certain section of the infoblock?
I found this code online:

<?
CModule::IncludeModule("iblock");
$BID = 2;   //ID инфоблока
$SID = 2;   //ID секции
$result = CIBlockElement::GetList(
   Array("ID"=>"DESC"), 
   Array("IBLOCK_ID"=>IntVal($BID), "ACTIVE_DATE"=>"Y", "ACTIVE"=>"Y","SECTION_ID"=>$SID), 
   false, 
   Array("nPageSize"=>3), 
   Array("ID", "NAME", "DETAIL_PAGE_URL")
);
while($arResultmy = $result->GetNext()){
echo '<div>'.$arResultmy['NAME'].'</div>';
}
?>

The code works, but I don't understand how using this code to display the created properties of the elements. Guys, help, who can))

In the settings of the news module (news.list) there is a section "Additional settings" .... there is an ID field. It is enough to specify the desired section ID and the module will display only those elements that are in this section.
