const handleCustomOnClick = async (event) => {
    if (performed.current) {
      performed.current = false;
      return;
    }

    event.preventDefault(); // Stop default behavior

    // Check if there is an old line with handle === "kit"
    const existingTableLine = lines.find(
      (item) => item.merchandise.product.productType === 'Style de kit',
    );

    // Remove the existing line with handle === "kit"
    if (existingTableLine) {
      await linesRemove([existingTableLine.id]);
    }

    // Add the new product
    const lineToAdd = selectedVariant?.id;
    const newProduct = {
      merchandiseId: lineToAdd,
      quantity: 1,
    };

    // Display loading message
    messageApi.open({
      key,
      type: 'loading',
      content: 'Chargement...',
    });

    // Delay for a smoother transition
    await new Promise((resolve) => setTimeout(resolve, 700));

    // Add the new line
    await linesAdd([newProduct]);

    // Display success message
    if (!existingTableLine) {
