Help! Interactive Image/PDF/Document annotation in VueJS/Laravel

I need to build an interactive "annotation/review" interface for a client of mine. Ideally, they want to have an image/document/pdf previewed on the left, which they can click and mark points on, and on the right display comments for each marker.

Has anyone seen/built/used a package which handles this? If not any idea how I'd even start to implement this? It's more the marking points part which is a head scratcher, as I can easily store x/y values and the comment in my DB.

My stack is VueJS on the front end, using Laravel on the back end.

Any help appreciated!
