Enable 2FA in shared mailbox

Hello,

"A shared mailbox is not designed for direct logon. The user account for the shared mailbox itself should stay in a Disabled (or "disconnected") state."

"A shared mailbox is a type of user mailbox that doesn't have its own username and password. As a result, users can't log into them directly."

What about MFA for the users accessing the shared mailbox?
