Home Custom Menu Link

Hi there, I’m trying to have the menu link per default when using my custom menus, and in my functions document I have this:

function home_page_menu_args( $args ) {
$args['show_home'] = true;
return $args;
}
add_filter( 'wp_page_menu_args', 'home_page_menu_args' );

The thing is, in the custome menu options > pages I have this: “No items.” So not sure what’s going on, it was working in other websites but not in this one, any idea?

Thanks!

A.
