Hi there,
I had try the demos for pdf viewer for Angular and found out that the annotations delete is actually not working. Please check on it and advise on which file should I change in order for it to work.
Steps to reproduce error
1)Open the pdf viewer
2)Click "Add or Edit annotations"
3) Create an annotation inside the pdf.
4)Right click that annotation and press delete.
5)Not able to delete.
6)Click the annotation and click on the delete icon.
7)Also not able to delete.
