Support for <!--nextpage--> (Page Break)

I want the ability to split a very long post into multiple pages, similar to the page break block in Gutenberg. I've been googling about this for a long time and have also asked Elementor support, and I'm shocked to find that such an essential thing is not included in Elementor, even in Pro.

Whenever I ask support how to do it, they just tell me to add pagination to a post widget... which is not what I want to do.
