Post Carrousel , taxonomie and Post in Value

Hello,

thank you for this wonderful extension!

To modify Posts Caroussel, I use the “Custom Query” source,
but if I select “Post Type” and “Pages”; but it does not offer the category pages in the “Taxonomies” but the “Category” … How to do it?

Otherwise I had thought of adjusting the source: “custom Query”, post types: “Pages”, post in: page id 28, page id 35, etc. but it doesn’t work either; what is the syntax for the Post In value?

thank you so much

Henry
