How to add Fingerprint AIO to an existing Ionic React project

Hi guys,

I am trying to add Biometric login to my web-app. The issue is that I had introduced ionic inside an already existing react-app. So I don’t have capacitor or cordova. I am trying to follow the capacitor steps mentioned in this https://ionicframework.com/docs/native/fingerprint-aio

However, upon running ionic cap sync, I get ionic is not found. Have I missed something while installation? The @ionic/react library works great and I haven’t had to use ionic command till now as I am not building any native app but just deploying them to the web. Please help me get started, much appreciated!

try npx ionic cap sync
