students editing whiteboards outside of the zoom session

[lilmelissa1]

I'm having trouble setting up the whiteboard such that my 11 yr old students can access and edit the whiteboard outside of our Zoom class time.  

I have selected anything in settings that looks like it would allow me to do this.  But, in the whiteboard sharing default section of the settings, it won't let me select "anyone" can access.  It says "your admin has disables this setting" but I am the admin and I don't see another place where I can enable it.

I have tried sharing the link to the whiteboard in my Google Classroom.

Does the student need to have a Zoom account in order to access the whiteboard outside of class?  Do they need to use the same email address to sign into their Zoom account that they use when they click into our Zoom class?

Thanks so much!
