sharing my onenote notebooks through onedrive

The directions on the "move a Onenote notebook to Onedrive" page of support leave me quite perplexed. When I select "share" in my on note 2016 file menu, there is nowhere a "select a location" option, or an "add a place" menu item. 

 I am a regular office365 user, so I must have the standard 2016 Onenote edition.
Does anyone have a clue, on how to move my notebook to OneDrive?
