Post Grid with Include by ACF field

I'd like to have a Post Grid with the following settings: Post Type = picking a CPT Select posts by = "Query" (new feature =>) Include by ACF field = select ACF field and which value it needs to have. Context: – I have a CPT for Books and a Chapters CPT. – Each chapter has a Chapter.Book ACF "post object" field which tells me which book it's from. – I want to create a page with: -— Heading: Book 1 -— A post grid displaying all chapters from Book 1. — Heading: Book 2 — A post grid displaying all chapters from Book 2. — and so forth. Thanks!
