Display Posts from Single Category

I looked through your docs and it said to use the_loop_wp_tiles() (eg. https://generatepress.com/forums/topic/wp-tiles-on-category-archive/), and then I can do a shortcode [wp-tiles posts_query=”category=30″], but the_loop_wp_tiles(‘content’, get_post_format()) throws a fatal error. How can I display posts from just 1 single category? Also, how can I setup category pages to shows tiled posts?

Thanks!
