Sharing OneNote Notebook through API

Question

As per the link to "Create sharing links on OneNote entities", it appears the OneNote API only supports sectionGroups.

POST ../sectiongroups/{sectiongroup-id}/Microsoft.OneNote.Api.GetOrCreateAnonymousSharingLink

It however seems possible to create a link to a notebook (or section) with the OneDrive API

POST ../sites/{site-id}/drive/items/{item-id}/createLink

Is there a problem with using the API this way (particularly as my notebooks don't have section groups)?
