remove_submenu_page not working

I have the following code:

add_action( 'admin_menu', 'tcd_remove_admin_menus', 999 );
function tcd_remove_admin_menus() {
    if ( current_user_can('shop_manager')){
   		remove_menu_page('edit.php');   
    	remove_menu_page('upload.php');   
    	remove_menu_page('tools.php');
    	remove_menu_page('edit-comments.php');
        remove_menu_page('users.php');
        remove_menu_page('yikes-woo-settings');
        remove_menu_page('wpseo_workouts');
        remove_menu_page('edit.php?post_type=product');
        remove_menu_page('edit.php?post_type=page');
        remove_menu_page( 'avada' );
        remove_menu_page( 'wc-admin&path=/analytics/overview' );
        remove_submenu_page('woocommerce', 'wc-admin');
        
        remove_submenu_page('woocommerce-marketing', 'edit_shop_coupons');
	}
}

and the only line that doesn’t work is remove_submenu_page(‘wc-admin’, ‘edit_shop_coupons’); I’ve tried multiple things but no success…

I am trying to remove a submenu Under Marketing (admin.php?page=wc-admin&path=/marketing) > Coupons (edit.php?post_type=shop_coupon)

Then I added a code to return the submenus array and I got this:

    [woocommerce-marketing] => Array
        (
            [0] => Array
                (
                    [0] => Overview
                    [1] => view_woocommerce_reports
                    [2] => admin.php?page=wc-admin&path=/marketing
                    [3] => Overview
                )

            [1] => Array
                (
                    [0] => Coupons
                    [1] => edit_shop_coupons
                    [2] => edit.php?post_type=shop_coupon
                    [3] => Coupons
                )

            [2] => Array
                (
                    [0] => Gift Cards
                    [1] => manage_woocommerce
                    [2] => gc_giftcards
                    [3] => Gift Cards
                )

            [3] => Array
                (
                    [0] => Activity
                    [1] => manage_woocommerce
                    [2] => gc_activity
                    [3] => Activity
                    [4] => hide-if-js
                )

        )

How can I remove Array[1] from the menu?
