Not sure if this is a log that Android 14 exposed but when I first got my 7a I could not get fingerprint actions working. Anyway it works now.

When setting a Logcat Entry event under Profiles, search for a “Biometrics/AuthenticationClient” Component in the log. Then try filtering for something like “onAuthenticated(true), ID:123456789”, the individual finger ID. Tasks can then be fired off on unlock.
