[local_auth]how to detect the changes of user's bio info

[justsonghua]

i try to do a func that when user change the bio info like face id or fingerprint, then when i call LocalAuthentication().authenticate(), i can get a flag or token so i can notify my users that the bio info had change, this time need to use passcode to do the verfy. But currently LocalAuthentication().authenticate() only return a bool, i wonder is this only can do by Object-C or Kotlin, thank you
