Are you sure you need the Microsoft one? After reading the giant support document at my employer I eventually figured out that any TOTP supporting app would work but most of the documentation made it sound like Microsoft was required anyway.

This depends on how the organization configures things. My company used to allow TOTP so many TOTP apps could be used instead of Microsoft Authenticator but my company disabled that a while ago. Now the only authenticator app my company allows is Microsoft Authenticator using push notifications (see https://learn.microsoft.com/en-us/entra/identity/authenticat... ). Consider yourself lucky if your employer allows you to use any TOTP app you want instead of forcing you to use Microsoft Authenticator.

it seems to be a push notification where the ms authenticator doesn't generate a code until I first log into the vpn using exchange creds but tbf, I didn't look hard enough for alternatives so you are probably right that I could use any totp app.
