How to take over as the host in the absence of the original host

Hello,

We have a recurring monthly meeting with external sponsors and the zoom meeting details that have been given out are the "owner" of the zoom account.  Unfortunately he had a medical emergency and is out for the next few days.  I'm an admin on the account - is there any way I can "take over" his account so I can proctor the meeting tomorrow instead of having to send out new zoom details?  Our fear is that there are quite a few members and we don't want to confuse folks with the revised invite.
