When I upload digitally signed document on PDF JS EXPRESS, I have “sign here” annotation ( e signature field ) instead of digital signature. I know that PDF JS EXPRESS doesn’t support digital signature in this moment but can you please help me to delete “sign here” annotation??

Thank you so much,  
Stefan

Hi Stefans,

You can remove the sign here annotation by iterating over all the annotations and seeing which one is a signature annotation and removing it if it is a signature annotation. Here is a code snippet to do just that:

```javascript
const { docViewer, annotManager, Annotations } = instance;
     docViewer.on('annotationsLoaded', () => {
       const listOfAnnots = annotManager.getAnnotationsList();
       listOfAnnots.forEach(annot => {
         if (annot instanceof Annotations.SignatureWidgetAnnotation)
           annotManager.deleteAnnotations([annot]);
       });
     });

```

Cheers,  
Dustin
