Insert HTML in docx file

I have made an application that fills wordfiles with customxmlparts now I am trying to put text into a textfield, but it has HTML in it and I want it to show the styling of it. I tried converting it to rich text format but that just gets pasted in the word file. Here is an example of the code:

var taskId = Guid.NewGuid();
var tempFilePath = $"{Path.GetTempPath()}/{taskId}";

using (var templateStream = new FileStream($"{tempFilePath}.docx", FileMode.CreateNew))
{
    templateStream.Write(template, 0, template.Length);
    // 1. Fill template.
    using (WordprocessingDocument doc = WordprocessingDocument.Open(templateStream, true))
    {
        MainDocumentPart mainDocument = doc.MainDocumentPart;

        if (mainDocument.CustomXmlParts != null)
        {
            mainDocument.DeleteParts<CustomXmlPart>(mainDocument.CustomXmlParts);
        }
        CustomXmlPart cxp = mainDocument.AddCustomXmlPart(CustomXmlPartType.CustomXml);
        foreach (var line in data.Lines)
        {
            if (line.MoreInfo != null && line.MoreInfo != " ") {

            }
        }
        var xmlData = ObjectToXml(data);

        using (var stream = GenerateStreamFromString(tempFilePath, xmlData))
        {
            cxp.FeedData(stream);
        }

        mainDocument.Document.Save();
    }               
}

You can't just write the HTML formatted text into a DOCX field, you would need to convert it into a WordprocessingML format.
However, there is another way that you could try and that is to insert an "AltChunk" element. That element represents a sort of like a placeholder which can reference a HTML file and then when the DOCX file is opened in MS Word, it will make that HTML to WordprocessingML conversion for you. For details see: How to Use altChunk for Document Assembly

Alternatively you could use some third party, like GemBox.Document, which can make that HTML to WordprocessingML conversion for you.
For example check this Set Content example:

// Set content using HTML tags
document.Sections[0].Blocks[4].Content.LoadText(
    "Paragraph 5 <b>(part of this paragraph is bold)</b>", LoadOptions.HtmlDefault);
