Change your view to Draft, select the References tab of the Ribbon, and then Show Notes, choosing Endnote area in the dialogue that pops up. At the bottom of the page, in the gray bar, use the dropdown arrow to select Endnote separator. Delete the line and type Notes, with a line space after it.

Return to Page layout view.
Done.
