Configure TOTP from within the app in Amplify UI v2

I'm trying to upgrade Amplify UI to v2 and since `AmplifyTotpSetup` has been removed from '@aws-amplify/ui-react' package, the question is what is the replacement for that in v2 to use it in ?

I want to allow my users to set up their 2FA from within the settings page of my app (i.e. not from the login page itself). For this, I want to show only the TOTP setup view from Amplify-UI - not the login/sign-up/etc view.
With Amplify-UI v1, I used the `AmplifyTotpSetup` as a standalone component to achieve this:
```
import { AmplifyTotpSetup } from '@aws-amplify/ui-react';

loadCognitoUser()}
className={classes.mfaEmbed}
/>
```

I already tried these:
- Finding the element that was used in Amplify v1 (`AmplifyTotpSetup`)
- Using Authenticator with initial state, but there is no initial state supported for Totp (`initialState?: 'signIn' | 'signUp' | 'resetPassword'`)

Any guide would be appreciated.

Start with the v2 Authenticator entry point and the removed AmplifyTotpSetup component in @aws-amplify/ui-react, then review the related issue 1150. Determine whether v2 supports rendering only the TOTP setup flow from an account settings page rather than through login or sign-up. Done means the supported replacement or its absence is documented clearly.
