How to allow staff to schedule your zoom meetings keep you as the host?

We have a pro membership and I have been scheduling my own meetings with participants. I need for my staff to be able to schedule my meetings for me when they make appointments but allow me to continue to be the full and only host of the meeting (unless I pass it on to somebody else).   I am the "licensed" user of the software and they have "guest" membership status under my license.  Do I need to purchase a license for each person to be able to schedule meetings for me or can I give them some kind of permission?
