Updating/filling Bitrix price types?

Question

1C-Bitrix

Good afternoon! Please tell me, I'm trying to collect a subscription to an event when converting the exchange rate!

1. Added new Price types: USD, EUR
2. Therefore, the product has new price types: USD, EUR

Task: Update \ fill in these price types for the product when updating the exchange rate in terms of the base one at the established exchange rate.

In init.php I began to think something like

AddEventHandler("currency", "OnCurrencyRateUpdate", "CurrencyUpdate");
function CurrencyUpdate()
{
    CModule::IncludeModule('iblock');
    CModule::IncludeModule('catalog');
    CModule::IncludeModule('currency');

    $obElements = \Bitrix\Iblock\ElementTable::getList([
        'select' => ["ID"],
        'filter' => ["IBLOCK_ID" => 1]
    ]);

    $el = new CIBlockElement;
    while ($result = $obElements->fetch()) {
        $el->Update($result["ID"], []);
}

This is the implementation of dynamic multicurrency on the site by the selector.
In the smart filter, it is necessary to display the currency, which was successfully done, but there was a difficulty with filling in these prices in currencies.
There are very few examples, information on the Internet ..
It doesn’t work, I will be grateful for tips, help ...

Go through the prices with the desired type and update, you don’t need to touch the elements themselves, the price is stored separately: https://dev.1c-bitrix.ru/api_d7/bitrix/catalog/pri...
