Default WP gallery with pagination?

Question

WordPress

Good afternoon! It is necessary to implement the default gallery of the WP with pagination, I would like it without plugins. I found a ready-made solution ( here it is ), but it is not suitable for the gallery inside the POST, and not inside the page. As I understand it, there are some problems with rewrite rules, because if you turn off the CNC, pagination starts working.
Can someone come across other solutions or can suggest what to fix in this?

Answer 1

Why pagination in the default gallery? She's not meant for that. Don't be bullshit.
