This web part provides you the ability to display a list of a particular user’s recently visited sites on a web page. The web part will display up to the first 30 (thirty) recently visited sites at a time. This web part is powered by the Microsoft Graph and currently requires that the Office 365 tenant be configured for targeted release for all users.
