Get a category or post with tailor

I discovered Tailor with great pleasure. Thank you for this very powerful instrument.
My problem is that I can’t seem to appeal to a particular category. For example: on my homepage, I would like the carousel to display images from posts in the landscape category.

I try with collection and section components… nothing to do.
Same thing if I want to display a particular post in an insert.

Could someone help me and tell me how to do it? (if possible with Tailor!)
