How to make the numbering bold in List in iText7?

Question

I am using List class of iText7 to create an ordered list in a PDF. The text in the List can be made bold easily but not the numbering. If I apply SetBold() to the List object every item added to the List object gets converted to bold as well. I just want to make the numbering of the ordered list in bold. How can I achieve this?

The code that I am using

using (PdfDocument pdfDocument = new PdfDocument(new PdfWriter(filePath)))
{
    using (Document document = new Document(pdfDocument))
    {
        List header = new List(ListNumberingType.DECIMAL);

        for (int i = 0; i < 10; i++)
        {
            ListItem li = new ListItem();
            li.SetKeepTogether(true);

            li.Add(new Paragraph("TableName").SetFontSize(13)
                                             .SetBold());

            li.Add(new Paragraph("Hello")).SetFontSize(13);

            header.Add(li);
        }                   
        document.Add(header);
    }
}

The output that I am getting

My desired output

In the desired output the numbering of the list is in bold

This is a Java example to achieve the desired result and I hope you can easily adapt it to your programming language

try (PdfDocument pdfDocument = new PdfDocument(new PdfWriter(outFileName))) {
            try (Document document = new Document(pdfDocument)) {
                List header = new List(ListNumberingType.DECIMAL);

                for (int i = 0; i < 10; i++) {
                    ListItem li = new ListItem();
                    ListItem li2 = new ListItem();

                    li.add(new Paragraph("TableName").setFontSize(13)
                                    .setFont(PdfFontFactory.createFont(StandardFonts.HELVETICA_BOLD)))
                            .setFont(PdfFontFactory.createFont(StandardFonts.HELVETICA_BOLD));

                    li2.add(new Paragraph("Hello")).setFontSize(13)
                            .setFont(PdfFontFactory.createFont(StandardFonts.HELVETICA));

                    li.add(li2);

                    header.add(li);
                }
                document.add(header);
            }
        }

My output result
