activateBiometrics
Activate the biometric authentication as a means of convenience to verify the user presence, so that the user doesn't have to enter the PIN to unlock the SDK. This method shall only be called when the SDK LockConfigurationType is SDK_PIN_WITH_BIOMETRICS_OPTIONAL.
This is a protected operation, so the SDK must be unlocked before calling this method.
Parameters
a configuration for a system biometrics prompt.

if the SDK is configured with a LockConfigurationType other than SDK_PIN_WITH_BIOMETRICS_OPTIONAL.
if the SDK cannot retrieve the SDK PIN from memory
