Replace product title with product sku

Hello,
I have to replace the product title with the product sku on the cart page when the quantity of the product is not enough.
In class-wc-cart.php at line 789 i found the code to customize:

if ( apply_filters( 'woocommerce_cart_item_required_stock_is_not_enough', $product->get_stock_quantity() < ( $held_stock + $required_stock ), $product, $values ) ) {
				/* translators: 1: product name 2: quantity in stock */
				$error->add( 'out-of-stock', sprintf( __( 'Sorry, we do not have enough "%1$s" in stock to fulfill your order (%2$s available). We apologize for any inconvenience caused.', 'woocommerce' ), $product->get_name(), wc_format_stock_quantity_for_display( $product->get_stock_quantity() - $held_stock, $product ) ) );
				return $error;
			}

Serching on google, I found this hook:

function filter_woocommerce_cart_product_not_enough_stock_already_in_cart_message( $message, $product_data, $stock_quantity, $stock_quantity_in_cart ) {
    // New message
    $message = __( 'You are currently trying to order more of this product than are currently available at your shipping location. Please call our sales team to discuss availability', 'woocommerce' );
    
    return $message;
}
add_filter( 'woocommerce_cart_product_not_enough_stock_already_in_cart_message', 'filter_woocommerce_cart_product_not_enough_stock_already_in_cart_message', 10, 4 );

but it doesn’t work.
Anyone knows hot to do it?
thanks.
