Send an invitation link to OneNote Class user again

Concerns One Note Class: I created a notebook and invited a group of students. All worked well - but at least one student deleted the invitation link to the book which is sent by e-mail. At the moment she has no access to this notebook (she cannot find the book on her tablet app).

Is there a way to sent her the invitation link to the notebook again?

(I added the class as a group to the notebook - so I do not see a way to remove her individually and add her again).

Thanks for help!
