Как получить двойное главное навигационное меню с брендом в центре начальной загрузки 4 WordPress с Navwalker

Я пытаюсь создать главное меню навигации для темы WordPress Bootstrap 4, над которой я работаю. У меня есть небольшая кобыла, заставляющая отображать меню, и я надеюсь, что кто-то может мне помочь.

По сути, мне бы хотелось, чтобы изображение в центре меню было ориентировано на бренд и чтобы меню располагалось по обе стороны от меню. При сворачивании оба меню должны быть видны в пределах одного и того же выпадающего меню. В настоящее время я не могу получить второе меню для отображения.

Пока я здесь, ниже приведены фрагменты соответствующих файлов. Очень ценю усилия тех, у кого есть время помочь.

functions.php

// This theme uses wp_nav_menu_left() in one location.
register_nav_menus( array(
    'main-left' => esc_html__( 'Main Left', 'wp-bootstrap-starter' ),
) );

// This theme uses wp_nav_menu_righ() in one location.
register_nav_menus( array(
    'main-right' => esc_html__( 'Main Right', 'wp-bootstrap-starter' ),
) );
