Facebook store collection?

Question

PHP

Hi guys.

We unloaded our products from the Facebook store via feed xml. All OK.

<item>
    <g:id>12038</g:id>
    <g:title>название</g:title>
    <g:description>описание/g:description>
    <g:link>https://site.ru/produktyi/ukrasheniya/brastetyi/bez-kamnej/kolczo-molniya-black/</g:link>
    <g:image_link>https://site.ru/upload/iblock/dcf/dcfdad1f165ed49d1656d6a5d916ffd5.jpg</g:image_link>
    <g:brand>KV MODE</g:brand>
    <g:condition>new</g:condition>
    <g:availability>in stock</g:availability>
    <g:price>1500.00</g:price>
    </item>

Now we want to create groups


What is already on the screenshot somehow created itself .....

Naturally, we are lazy people and customers too, and there are quite a few groups. We want to automate.
As far as I understand it is either created manually or via api.
I found the official library https://github.com/facebook/facebook-php-business-sdk
But how to create groups through it, or at least through this library to load the products that we unloaded from the feed file for the corresponding groups, remains a mystery to me.

I would appreciate any help.....
