How to Get The Excerpt of the page that displays Blog Posts

I use a static page (Blog) to display the latest posts. I want to show the excerpt of that page next to the title. However, wen I use wp_kses_post( get_the_excerpt() ), I get the excerpt of the latest post from the post archive loop. I also tried with wp_kses_post( get_the_archive_description() ) but it also does not seem to work.. Any idea how this can be done?

Admin Filter – Add Post Type Description on Post Type Page

WordPress allows adding descriptions to Custom Post Types whenever it’s registered. ( register_post_type(). I would like to output that title on the Admin Landing Page ( View All Post Type ) preferably underneath the title. I’ve looked into /wp-admin/edit.php but I’m not sure if the filter presented is usable in this case ( and thus it may not be possible to do ).
