React Native - LocalAuthentication with FaceId in Android

I'm using expo-local-authentication module for biometrics authentication. I want to authenticate user with FaceId in my android device.

As per the LocalAuthentication documentation, I'm using LocalAuthentication.supportedAuthenticationTypesAsync() method to determine what kinds of authentications are available on the device. In my devices it only returns [1]. which means my devices supports TouchID. If it returns [1,2] that means the device has both types supported (TouchId & Facial Recognition).

I'm wondering why it says my phone is only supporting TouchId. Even if i have face unlock feature in my device.

My device Info:

Model Name: Vivo Y83,
Model Number: vivo 182,
Android version: 8.1.0
