php wordpress woocommerce backend dashboard

Remove submenu for 'Add Order' in WooCommerce on WordPress admin dashboard

My WooCommerce version is 4.5.2.

I will like to remove the 'Add order' for a custom user so that it cannot access wp-admin/post-new.php?post_type=shop_order.

I have created a custom user using User Role Editor with the following permissions:

With this, the user can only view existing orders, and click the order preview to update to 'Completed'.

I tried using this:

remove_submenu_page( 'edit.php?post_type=shop_order', 'post-new.php?post_type=shop_order');

...but the Order main menu becomes not accessible.

I came across this post Remove or hide "add new" button on woocommerce on bulk order panel, which hides the 'Add order' from the page using CSS.

I wish someone can point me to a direction on how to achieve what I am looking for.

UPDATE:

Based on 7uc1f3r's answer, this is my output

[edit.php?post_type=shop_order] => Array
    (
        [5] => Array
            (
                [0] => Orders 
                [1] => edit_shop_orders 
                [2] => edit.php?post_type=shop_order
            )
            
        [10] => Array
            ( 
                [0] => Add order 
                [1] => edit_shop_orders 
                [2] => post-new.php?post_type=shop_order 
            )
    )

Using the provided solution, I use this so that the custom user cannot Add order and access wp-admin/post-new.php?post_type=shop_order:

    unset( $submenu['edit.php?post_type=shop_order'][10][0] );
    unset( $submenu['edit.php?post_type=shop_order'][10][1] );
    unset( $submenu['edit.php?post_type=shop_order'][10][2] );

In addition, I apply CSS to hide the 'Add order' at the admin panel:

    ul.wp-submenu.wp-submenu-wrap {
        display: none !important;
    }

It now looks like this:

Solution

I'm using WC 4.4.1 & WC 4.6.0 and in both versions there is no possibility to create a new order from the menu.

UPDATE: Due to the output you posted, this should suffice to remove "Order: add new"

function action_admin_menu() {
    global $menu, $submenu;

    // Unset 'Order: add new'
    unset( $submenu['edit.php?post_type=shop_order'][10] );
}
add_action( 'admin_menu', 'action_admin_menu' );

Optional: For "Products: add new" and DEBUGGING you could use

// DEBUG: This displays the complete wordpress admin menu on your dashboard for admin only. (Remove afterwards)
function debug_admin_menus() {
    global $menu, $submenu, $pagenow;
    if ( current_user_can('manage_options') ) {
        if( $pagenow == 'index.php' ) {  // print on dashboard
            echo '<pre>', print_r( $menu, 1 ), '</pre>'; // top level menus
            echo '<pre>', print_r( $submenu, 1 ), '</pre>'; // submenus
        }
    }
}
add_action( 'admin_notices', 'debug_admin_menus' );

function action_admin_menu() {
    global $menu, $submenu;

    // Unset 'Products: add new'
    unset( $submenu['edit.php?post_type=product'][10] );
}
add_action( 'admin_menu', 'action_admin_menu' );
