Adding a @mention functionality to the commenting system

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.)

Hi brandonmartin98,

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