How to print in italic using Docxtemplater libary

I’m trying to generate a Microsoft Word Document using docxtemplater library https://www.npmjs.com/package/docxtemplater. Here is how my code would look like (using in browser):

<script src="https://cdnjs.cloudflare.com/ajax/libs/docxtemplater/3.49.0/docxtemplater.js"></script>
<script src="https://unpkg.com/[email protected]/dist/pizzip.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/FileSaver.js/1.3.8/FileSaver.js"></script>
<script src="https://unpkg.com/[email protected]/dist/pizzip-utils.js"></script>

    <script>
        function loadFile(url, callback) {
            PizZipUtils.getBinaryContent(url, callback);
        }

        window.onload = function generate() {
        const data = "<i>some text with italic</i>";

        const file = "http://file-url";

        loadFile(file, function (error, content) {
            if (error) {
                throw error;
            }
            const zip = new PizZip(content);
            const doc = new window.docxtemplater(zip, {
                paragraphLoop: true,
                linebreaks: true,
            });

            doc.render({
                "data":data
            });

            const blob = doc.getZip().generate({
                type: "blob",
                mimeType:
                    "application/vnd.openxmlformats-officedocument.wordprocessingml.document",
                compression: "DEFLATE",
            });
 
            saveAs(blob, "output.docx");

        });
    }
    </script>

When i look at the word output, i expect it to look like “some text with italic”, instead of

<i>some text with italic</i>

How can i make text in the word output italic using docxtemplater library?
