DivElement Not getting displayed in tagged PDF

Hi Aspose Support,
I am using the following code to display divElement but i am not able to see anything in the generated pdf. Please let me know mistakes if any in the code and suggest the correct code.
Code
DivElement divElement = taggedContent.createDivElement();
taggedContent.getRootElement().appendChild(divElement);

@abrahamaby,

I create a very simple document with the following code:

C#

private void Logic()
{
    Document document = new Document();

    ITaggedContent taggedContent = document.TaggedContent;

    taggedContent.SetTitle("PDF with Tagged Content");
    taggedContent.SetLanguage("en-US");
    
    DivElement divElement = taggedContent.CreateDivElement();
    taggedContent.RootElement.AppendChild(divElement);

    // Save PDF Document
    document.Save($"{PartialPath}_output.pdf");
}

The code in java:

public void Logic() throws Exception
{
    var doc = new com.aspose.pdf.Document();

    ITaggedContent taggedContent = doc.getTaggedContent();

    taggedContent.setTitle("PDF with Tagged Content");
    taggedContent.setLanguage("en-US");

    DivElement divElement = taggedContent.createDivElement();
    taggedContent.getRootElement().appendChild(divElement);

    doc.save(PartialPath + "_output.pdf");
}

The output:
