Class Notebook- Student Privacy

Hello,

We want to use a Class Notebook to share information with students who are in quarantine, but without allowing other students to know who is also in the notebook. 

I tested this today and if they go to 'share' or 'manage access' they can see who else is a part of the class notebook. 

Is there any way to make the notebook completely confidential for HIPAA reasons? So, only each student sees nothing except what the instructor shares with them in their notebook section? So, they do not 'see' who else has access to the Class Notebook?

I'm not talking about seeing content, but actual student names- who else besides them are in the notebook. 

Thanks,
Debbie
