Can't find a plugin with the required functionality?

Question

WordPress

Good day, help me find a plugin with which a widget appeared in the standard block editor in wordpress, with which the editor can select the articles that he wants to add to the text of the post
Example in the picture below


and Here is an example live.
Reviewed all possible plugins ala related posts.
They basically add automatically at the end of the post, but I need the editor to be able to choose which posts he puts.

Specifically, in the Lifehacker example, this is most likely self-written functionality. Yes, and to implement such a thing is not so difficult. The same related posts, which is inserted with the news after a certain paragraph of text. And how exactly you implement it can be different... It can be some kind of shortcode (shortcode generator) or, for example, automatic insertion of a random article into a cycle, etc.
