In case you missed

As this plugin is created with custom post type, you can now add Gutenberg editor support for the plugin for writing the news post. For that, we have added apply_filters. For more details please check the plugin FAQ section.

apply_filters( 'sp_news_registered_post_type_args', $news_args ); 

Complete shortcode example:

[sp_news limit="10" category="category_id" grid="1"  show_content="true" show_full_content="true" 

Template code:

 <?php echo do_shortcode('[sp_news]'); ?>
