Adding annotations via addAnnotationsInPDF() is slow

Hi I'm currently using the PDF Embed API and I'm adding a hundred of shape annotations to a PDF (with a single addAnnotationsInPDF() call)  and it adds all the annotations visually, then adds one annotation at a time very slowly, that I can see following the triggered events and during this action it locks the application screen and take several minutes to complete. This makes the viewer barely usable for my application...
 
A JSON example of an annotation that is added:
