Admin panel to replace the image variations product

Hello. How to make sure that the main picture of the product is displayed in the admin panel Woocommerce-Order when ordering, and not its variations?

function getCartItemThumbnail( $img, $cart_item ) {

    if ( isset( $cart_item['product_id'] ) ) {
        $product = wc_get_product($cart_item['product_id']);

        if ( $product && $product->is_type( 'variable' ) ) {
            // Return variable product thumbnail instead variation.
            return $product->get_image();
        }
    }

    return $img;
}

add_filter( 'woocommerce_cart_item_thumbnail', 'getCartItemThumbnail', 111, 2 );

I changed it on the store page using this code. But it didn’t work in the admin panel. Please help me how to fix this. Thanks.
