<?php
// print_r(get_queried_object_id());
$primaryNav = wp_get_nav_menu_items(2);
print_r(get_menu_parent(2));
foreach ($primaryNav as $navItem) {
  if (!empty($navItem->menu_item_parent) && $navItem->object_id == get_queried_object_id()) {
    echo '<span>' . get_post($navItem->menu_item_parent)->post_title . '</span>';
  }
} ?>

So far in the page I got the parent menu name with object_id.

However, if you go to the post-type page from the menu, the object_id is 0, so the parent menu cannot be imported. What do I need to fix

I found a solution through the answers to the above questions.

function my_menu_parent($theme_location) {
    $locations = get_nav_menu_locations();
    if ( isset( $locations[ $theme_location ] ) ) {
        $menu = wp_get_nav_menu_object( $locations[ $theme_location ] );
        $menu_items = wp_get_nav_menu_items($menu->term_id);
        _wp_menu_item_classes_by_context( $menu_items );
        $breadcrumbs = array();

        foreach ( $menu_items as $menu_item ) {         
            if ($menu_item->current_item_ancestor) {
                $breadcrumbs[] = $menu_item->title;
            }
        }

        return $breadcrumbs;
     }
}

<?php
$parentitems = my_menu_parent( 'menu-1' );
foreach ( $parentitems as $parentitem ) {
    echo $parentitem."<br>";
}
