Rodrigo, there’s a few ways to achieve that.
1 – Using your category a good solution might be WP Show Posts, a plugin made by Tom for displaying posts everywhere on your site. https://wordpress.org/plugins/wp-show-posts/
2 – Also this plugin has a very similar way of GP KB, but I never tested: https://br.wordpress.org/plugins/wp-knowledgebase/
Hope I’ve helped
