Login problem " We detected an unusual sign-in from a device or location you don't usually use."

We are a small non-profit with a Zoom Pro account that we share amongst different people.  That is, we have a number of different meetings all owned by the same Zoom account, but  different people run them and all those people have a need to log into Zoom using our one Zoom Pro account in order to run the meeting as Host..    Let's say that the one Zoom account is "***********" and note that one person only can log into that email.

Today, for the first time, someone got the message, "We detected an unusual sign-in from a device or location you don't usually use. If this was you, enter the code below to sign in to Zoom"  and, of course, Zoom sent the code to *********** but the person running the meeting was not the person who has access to the email!

You see the problem.  How can we turn off that security email?  I am aware that if we enable 2 Factor Authentication the verification email will not be used - but I don't think that solves our problem because each of the people who might need to run the meeting has to have access to that same 2FA SMS phone number or authenticator - so 2FA isn't going to work either.

We want to turn off that security email.  How can we do it?  This is a big issue for use as you can imagine.
