[Plugin: Get Custom Field Values] Using with wp list pages

Hello everyone,
I find this plugin amazing and I managed to do some of the things I was planning already. (Info by the side, with icons, at https://gabriel-leveau.com/gab/brasil/balloon-ride)

But I miss a guide to all the usages, some kind of reference for using it.
Otherwise, only programmers will be able to take advantage of all its functionalities. I’m not complaining here, it’s just a suggestion. ; )

Since I’m not a real programmer, please allow me to ask:
– How to use it with wp list pages?

The website is https://www.brasilautentico.com and each category shows its posts in an image gallery. Instead of the date of the post (original value from template), I wanted to show the price of each product.

So the function should work with wp tag wp_list_pages in order to show the result of Custom Value = price for each post, everytime.

What’s in there at the moment shows the same info for all posts. I used search randomly since I didn’t know how to do it.

Could anyone help?

Thanks in advance.
