Tabs (tabs) with pagination for WordPress or a "load more" button?

Question

WordPress

Kind.
I made a website with tabs through mixitup ( https://github.com/patrickkunka/mixitup)
I put it on WordPress, but I don’t understand how to attach pagination (WP-PageNavi) or the “load more” button normally in tabs.
Pagination works, but very crookedly.
Tell me a working version (plugin is possible) of tabs with pagination or the "load more" button.
Thank you!
