How to add Office365 Exchange shared mail accounts with MFA on MacOS Monterey Mail 15.0 ?

Hello,

As the title says, how can I add an shared email account with MFA that is on Office365 Exchange?

So I have my account to login on Microsoft Office365, that is the user, then I have access to about 10 other shared mail accounts, on Outlook is pretty forward, just add email I want and then login with my account, but for Mail I can only add the main account (user) that has previous accepted by admin, but the shared ones, every time I change the mail for login, it says already exists or gives error if I try with different email.

I tried both [Microsoft Exchange] (through Configure Manually and Sign In) and [Other Mail Account...] options.

On previous version MacOS Big Sur & Mail 14, I could access because we didn't have MFA activated, but for obvious security reasons has been activated and now I can only access through Ms Outlook.

How can I configure or there is no way around?
