Add Product images (Drupal Commerce) to sitemap xml hooking

Hi all,

I've been trying to show the images of my products in the xml sitemap for a long time but I can not get it.

I managed to show the images of the nodes of the type articles following the following example:
https://hardcoredev.com/blog/add-images-to-sitemap-xml-hooking-into-xmlsitemap-in-drupal/ but in the products (Product Display) does not work.

I use Drupal commerce and I think it's because it uses Products reference fields to show images.

I need some help.

Any ideas?

Thanks!
