enrol ipad as shared ipad (education)

I have an ipad that is synced from apple school manager to manageengine. The ipad is in a group and has profiles, it has been working just fine in 1:1 mode.  I wish to change the ipad into a shared user ipad (in reality only two users will be using the ipad) - I am happy to factory reset.  How do I go about setting up a shared ipad?  I cannot fin any help or documentation on this.
