having someone else run my meeting if I am away

[fitnessfigures]

How does the "additional users" feature on a Zoom account work?  I have a licensed Zoom account and I have several recurring meetings set up.  I am planning on being away for a couple of the meetings and would like my assistant to run the meeting.  I did not necessarily want to hand over my login and passwords to her.  I don't want the possibility of settings to inadvertently get changed.  I see that additional users can be set up with different authority levels.  Is that what I need to do?  Is that what the additional user feature is for?

I don't want to mess around with a setup not knowing what I am doing.  Can anyone help me understand how to use this feature?
