TFA in NC30 with Microsoft Authenticator or similar Apps

I just set up a new Nextcloud 30 and want to enable TFA using Microsoft Authenticator. I had this running on my previous NC, but the needed App seems to be no longer available in Nextcloud App Store.
How can I enable this again, what app do I need now?

(Also eMail TFA app isn’t updated to NC30 so far (but may hopefully work).)

You must use the app Two-Factor TOTP Provider. This is in Nextcloud 30 a standard app for 2FA. You only must activate the app and then configure the entries in the security options.

Thanks, didn’t notice that it’s installed by default and needs just to be activated. I searched the store to install it…
