EXMAGE – for integration with other Plugin Import

I didn’t find the EXMAGE plugin in the drop-down list.
Then I inserted the plugin that I use it with.

I have a problem: SITUATION
I have an external Product Import plugin:
“Import, Export, or Update WooCommerce Products”
https://www.webtoffee.com/product/product-import-export-woocommerce/

When I import or update the products (and the image field), even if the product’s Aliexpress links are present, –> it copies the images on the site. Can you give me 2 tips for incorporating it?
For example in which part should I insert this code. In the Hook before CSV upload?

Thank you
