Unfortunately this plugin does not support pagination.
You can use the
posts_per_page parameter to decide how many posts to display on the current page, Display Posts will not add previous/next links below this list to explore further.
I’m planning to build a Pagination Extension in the near future, once I’ve finished building the Gutenberg block for Display Posts. You can follow its progress in the link above.
If you’re a developer, I invite you to join the GitHub discussion and contribute thoughts and code.
