How to delete a book in a team collection?

L.S. We are trying to delete books in our team collection. Following the steps in the manual does not work as there is no delete option in the right-click menu :

Can the manual be updated with instructions on how to delete a book in a team collection?
Much appreciated.
Bart.

In a team collection you must check a book out to delete it. This makes sure that no one else is working on it.

Sorry, that’s a bug that Delete was being hidden, instead of disabled. We’ll get that fixed.

Merci beaucoup John.
Have a good weekend.
