Face recognition in android

[leilenmapplics]

Hi!
I'm trying to use this plugin in one of the proyects.
I can successfully check if fingerprint recognition is available, and i can also show the modal and login.
When i built it for android, and install the apk, although i have all the permissions, i dont see the option to log with face recognition.

The code i use:

this.faio.show({ title: 'Biometric Authentication', subtitle: 'Coolest Plugin ever', description: 'Please authenticate' , fallbackButtonTitle: 'Use Backup', disableBackup:true, })

I also reinstalled and built platform again.

Ionic CLI : 6.12.3
Ionic Framework : @ionic/angular 4.1.1
@angular-devkit/build-angular : 0.13.6
@angular-devkit/schematics : 7.2.4
@angular/cli : 7.3.6
@ionic/angular-toolkit : 1.4.1

I've tested it in Xiaomi Redmi Note 8 and Xiaomi redmi note 7. Both are Android devices.

Thanks in advance!
