Imported polygon annotation is not showing

I have a PDF and i want to import annotations from a XFDF file,
the code i am using with Aspose.PDF 25.2.0
Document pdfDocument = new Document(inputPdf);

        // Create a PdfAnnotationEditor object
        PdfAnnotationEditor annotationEditor = new PdfAnnotationEditor();

        // Bind the input PDF
        annotationEditor.BindPdf(pdfDocument);
        using StreamReader reader2 = new("FIVR_133_PrintToPDF2.XFDF");
        // Read the stream as a string.
        string text2 = reader2.ReadToEnd();
        using(MemoryStream ms1= new MemoryStream(Encoding.UTF8.GetBytes(text2))){
        // Import XFDF annotations
        annotationEditor.ImportAnnotationsFromXfdf(ms1);
        }

annotationEditor.Save(outputPdf);

I think it’s a general problem with the polygon annotation types, following exactly steps described at
Add Figures Annotations using C#|Aspose.PDF for .NET

for the generated PDF, open in Edge or Chrome browser, the annotation are not shown

using other third part PDF library, we don’t have this issue
