Product XML Sitemap file - How to include all product images?

Store Design

In the default xml sitemap file at the root domain:
www.example.com/sitemap.xml

There are listed these paths to four the sitemap files:
https://www.example.com/sitemap_products_1.xml?from=1234567891234&to=1234567891234
https://www.example.com/sitemap_pages_1.xml
https://www.example.com/sitemap_collections_1.xml
https://www.example.com/sitemap_blogs_1.xml

In the first sitemap file that contains all products, it includes one image per product. Like below example:

[https://www.example.com/products/item-1111](https://www.example.com/products/item-1111) 2021-10-05T09:57:39+01:00 daily [https://cdn.shopify.com/s/files/1/2222/6555/2053/products/item-1111-photo-1.jpg?v=1234567890](https://cdn.shopify.com/s/files/1/2222/6555/2053/products/item-1111-photo-1.jpg?v=1234567890) Item title text Item caption text

Unfortunatley, all my products have multiple images.

How can I update this XML sitemap file, so that I can include all image photos for all my products?

Appreciate any advice.
