How to add products in the lead if the lead is created with the "other" source?

From the store on modx in bitrix24 creates a lead via the API. It is created. everything is fine.
You still need to add products to that lead.

About the products was this:
The REST handler at /crm/configs/import/lead.php doesn't work with products. Heading into the lid, you can add the method crm.lead.productrows.set

Tell me how via the API to add lead products from the website on modx?
