Easiest Way to Create Annotations on Someone Else's Model

Say I find someone else’s Sketchfab model particularly interesting, but I’d like to add my own annotations to them. What is the easiest way for me to add the annotations I wish to their model?

Would I have to go through the “createAnnotation()” function in the Sketchfab Viewer API?

My goal is to allow a user on my website to click to create their own annotations on an embedded Sketchfab model that they don’t own.

Thanks in advance.


Sketchfab Viewer API is definitely the way to do that.
