Comment to non-shared user

Would like to be able to send a comment, via email address, to a non-shared user without giving them access to the sheet as a whole (as in I don't want them having any permissions at all, such as Viewer, Commenter, etc.). Have tried ticking the "Don't Share" box on the dialog box, however the comment isn't received when doing so.

Any way of making this happen?
