how to hide gift products in vendor stores

What do you mean by gift products?

Products that we do not sell but give as a free gift in addition to a purchased product.

But how those are different that others? Have you set price “0” for those or it’s a different product type?

I haven’t set no price at all + I marked free products as “hidden” + I have a sub-sub-category. Apart from that they are same as the other products.
Please have a look at the screenshot of the settings of a gift product: https://test2.your-local-hero.com/wp-content/uploads/2021/05/Bildschirmfoto-2021-05-13-um-11.47.36.jpg
I want to hide them in the shop, but they appear when I use the woolentor widgets
like on this page: https://test2.your-local-hero.com/shop-2/cote-dazur/
I took WL Universal Product Layout to build this page and it shows the free and hidden product as well. Here you will find the query settings: https://test2.your-local-hero.com/wp-content/uploads/2021/05/Bildschirmfoto-2021-05-13-um-11.55.32.png
So please let me know how I can stop displaying products that are marked as hidden.

Would you please be so kind as to help me with this problem?
