Adding a @mention functionality to the commenting system

Which product are you using?
PDF.js Express Viewer

PDF.js Express Version

UI version 8.1.0
Core version 8.1.1
WebViewer Server false
Full API false

Detailed description of issue
Is there a way to add a @mention functionality to the commenting system? If there isn’t, is there at least a way to separate the comments from other annotations and read the text content of the comment? This is so that with a bit of extra code, a sort of mentioning feature can be added to the PDF viewer.

Expected behaviour
It would highlight the name after the ‘@’ symbol like how one would see a notable difference in a chat application. (Note: This is only if a mentioning system can be implemented into the PDF Viewer.)

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

Hi brandonmartin98,

We have a guide at our sister product’s webpage here: Apryse Documentation | Documentation
But the API should be the same

Best regards,
