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?

How to hide description on categories and tags?

Does anybody know how I can hide the descriptions from view for the categories and tags for my website? I have searched for a while but can’t find any solutions. I would like it so that when they are clicked it just shows the categories or posts available, no description visible. Can someone show me how to do this please?
