Sharing a Zoom whiteboard after session is over; Zoom says administrator won't let me; I am admin

I want to share my Whiteboard with my students AFTER the session is over. I am able to share it with them during the session. I want them to have access to it later. Zoom says I can share it only with participants who are in my organization, as determined by my administrator. But I have no organization. I am a solo private tutor who uses Zoom. I am the administrator. 

How do I, as the administrator of my Zoom account, allow myself to share Whiteboards at the end of the session?

Thanks!
