**Which product are you using?**  
PDF.js Express Plus

**PDF.js Express Version**  
8.7.4

**Detailed description of issue**  
I have a signature field I added to a PDF through Adobe Acrobat Pro. The PDF Express WebViewer does not recognize this as a signature field with the “SignHere” tag. Is this not supported in PDFJS?

**Expected behaviour**  
WebViewer should display SignHere tag on signature field and allows for digital signature to be added.

**Does your issue happen with every document, or just one?**  
Every document

**Code snippet**

 JavaScript PDF Viewer Customize Forms Demo 
Customize Form Style Demo for PDF Viewer

```
<script>
  WebViewer({
    path: '../../lib', // path to the PDF.js Express'lib' folder on your server
    licenseKey: 'Insert free license key here',
    initialDoc: 'Affirmation Form Fields.pdf',
    config: 'config.js'
    // initialDoc: '/path/to/my/file.pdf', // You can also use documents on your server
  }, document.getElementById('viewer'))
  .then(instance => {

    // disable annotations
  //instance.UI.disableFeatures([instance.UI.Feature.Annotations]);

    // now you can access APIs through the WebViewer instance
    const { Core, UI } = instance;

    // adding an event listener for when a document is loaded
    Core.documentViewer.addEventListener('documentLoaded', () => {
      console.log('document loaded');
    });

    // adding an event listener for when the page number has changed
    Core.documentViewer.addEventListener('pageNumberUpdated', (pageNumber) => {
      console.log(`Page number is: ${pageNumber}`);
    });
  });
</script>

```
