Display Meta Description of the page/post on the Page Header Element

Something like this might help, then: https://stackoverflow.com/a/43718728

add_shortcode( 'page_hero_meta_desc', function() {
    if ( class_exists( 'WPSEO_Frontend' ) ) {
        $wpseo_object = WPSEO_Frontend::get_instance();
        $intro_text = $wpseo_object->metadesc( false );

        return $intro_text;
    }
} );

Thanks Tom

It works like a charm
