custom permalinks for specific category

Hi, I want to do if the category is “news” add /news-event/ before it. so “site.com/news-event/news/post-name/”.
This is what I have tried so far but it still not work.please help me if you see something might go wrong.

add_filter( 'post_link', 'custom_permalink', 10, 3 );
 function custom_permalink( $permalink, $post, $leavename ) {

    // Get the categories for the post
     $category = get_the_category($post->ID);
     if (  !empty($category) && $category[0]->cat_name == "News" ) {
        $permalink = trailingslashit( home_url('news-events/' . $category. '/' . $post->post_name .'/' ) );
     }
    return $permalink;
}

function rewrite_rules( $wp_rewrite ) {
    $new_rules['news-events/^news/([^/]+)/?'] = 'index.php?name=$matches[2]'; //change 'test' to your category slug
    $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
    return $wp_rewrite;
}
add_action('generate_rewrite_rules', 'rewrite_rules');
