Signals Notebook: How to remove the annotations of a chemical drawing?

Chemical drawing files can contain annotations that can affect working with the cdxml files with the API. The annotations can't be removed directly from ChemDraw JS but they can be removed editing the file in the desktop version using the 'Edit in ChemDraw Destop' option in Signals Notebook.

Steps: 
1. In the Chemical Drawing element click the option  'Edit in ChemDraw Desktop'
2. Wait for the file to open in the desktop application
3. Go to File > Document Annotations…
4. In the pop-up box click ‘Delete All’, then ‘Delete’ in the confirmation file, then ‘OK’ to exit the box
5. Go to File > Save
