PDFNet missing RubberStampAnnot Icon

Product: PDFNet Node

Product Version: 9.4.0

Please give a brief summary of your issue:
The PDFNet RubberStampAnnot only has haft icons compare to the Webviewer PDFTron pdfnet-node Class: RubberStampAnnot
PDFTron WebViewer Class: StampAnnotation

Please describe your issue and provide steps to reproduce it:
I would like to add the SH_ACCEPTED and SB_REJECTED icons

Please provide a link to a minimal sample where the issue is reproducible:

const st = await PDFNet.RubberStampAnnot.create(
  doc,
  await PDFNet.Rect.init(x - 23, y + 12, x, y + 2)
);
await st.setIcon(PDFNet.RubberStampAnnot.Icon.e_Approved);
await st.setContents(await st.getIconName());

instead of setIcon I should use setIconName

const st = await PDFNet.RubberStampAnnot.create(
  doc,
  await PDFNet.Rect.init(x - 23, y + 12, x, y + 2)
);
await st.setIconName('SBRejected');
await st.setContents(await st.getIconName());
