"Drafts" content type in Microsoft 365 portal?

In the midst of delivering an "Introduction to Microsoft 365" workshop yesterday, I noticed a new view in the "Quick access" section (see below) of the M365 portal/app. When I click on that view, I'm told "No drafts yet / Create a new raft to get started". "Draft" is somewhat vague since several apps allow users to save things in a draft state (Outlook messages, SharePoint pages/news posts, etc.), so I'm not sure what's supposed to be showing up there. For example, I know I have several draft emails and draft pages in a few SharePoint sites, but they aren't appearing there. I suspect this may be part of/related to the new SharePoint start page experience which (I think?) will allow people to create "personal" pages (which will be stored in their OneDrive site collection, like "personal" lists).
