Pagination to Onepress blog

Hello, trying to add pagination to blog (news) page. Installed wp-navi plugin, searching the follow tags to the theme to replace them with plugin’s code but cannot found even with String locator.
<nav class="navigation posts-navigation" role="navigation"><h2 class="screen-reader-text">Posts navigation</h2><div class="nav-links"><div class="nav-previous"><a href="https://www.example.com/news/page/2/">Older posts</a></div></div> </nav>

Any ideas?
Thanks
