Additional image issues

I was using another google feed plugin and it was separating additional images with commas.
Example;
website.com/wp-content/2023/image1.png,website.com/wp-content/2023/image2.png,website.com/wp-content/2023/image3.png
But google can’t read it. That’s why it gives an error. So I decided to use your plugin.
I got an output like this in your plugin.

<g:additional_image_link>https://hizlilisans.com.tr/wp-content/uploads/2022/12/microsoft-office-365-turkce-win-mac.jpg</g:additional_image_link&gt;

<g:additional_image_link/>

<g:additional_image_link/>

<g:additional_image_link/>

<g:additional_image_link/>

Some products have 5-6 pictures. In some products, 2-3.
Am I doing it right?
How do I list additional images seamlessly?

Actually, I can try, but Google sometimes suspends the account at the slightest mistake and I don’t want to make a mistake.
