Zoom Sub accounts and Users

Hello

I have a Zoom account and I allowed other users access for a non profit that I was running. After I resigned, I believe the other users created a sub account in the name of the non profit under my main account. I had no idea and it's been like that for a year, or so I suspect.

Can anyone tell me how to find out more information about this arrangement? I did not know this was possible and would like some direction.

Thank you
