Ionic biometric authentication in Ionic React applications

Hey, We are trying to implement biometric authentication in our Ionic Capacitor5 React application.
We checked the official Ionic Identity vault to do this, but it is very expensive.

Is there any capacitor pluging that can use to do the biometric authentication? Our application is running in a health care domain, so we are more concerned about its security.

Please let me know if you know any secure bio-metric plugin?
