How to change the UI of Bio Metric Authentication in LocalAuthentication

Hello Expo Forums,

I just started authentication flow and completed username and password flow in react native with expo bare workflow, but now I want to log in the users with the fingerprint, and I found this pretty much library for that and its too good with simple steps but I want to make that UI in a full screen similar to Whatsapp.

Currently, I am getting the below image in bottom and half of the screen size


but I want the full-screen UI, image is shown below

can I customize the default UI?

If yes, so how and where is the documentation of that?
