            // Creating a renderer to convert the HTML string to PDF
            ChromePdfRenderer renderer = new ChromePdfRenderer();

            // Convert HTML string to PDF
            PdfDocument pdf = renderer.RenderHtmlAsPdf(htmlContent);

            // Return the generated PDF file
            return File(pdf.BinaryData, "application/pdf", "generatedDocument.pdf");
        }
    }
