Jetpack visibility widget in Divi

Hi there,

I’m using Jetpack’s widget visibility function by with widget blocks in Gutenberg in Divi on my blog:

I want to display certain widgets in the sidebar (e.g. a post preview with image) only on particular posts (not pages).

Unfortunately I can only assign to posts page or post type: post across-the-board but not to particuliar posts.

Is there a way to do it?

Thank you for your help.
