[Support request] Using Hook Element for Custom Author Link on Posts

Hi there,

I’ve realized with GP Premium I can delete Code Snippets as I’m only using it for this one here:

add_filter( ‘generate_post_author_output’, function( $output ) {
return ‘Author: My Name‘;
} );

Can I add this code to a Hook Element like this instead? (https://imgur.com/a/ENkPJF3)

Thanks!
