Apple Authentication Button doesn't show up using expo-apple-authentication package

I'm trying to implement Apple Sign In in my iOS app using the expo-apple-authentication package, but I'm not being able to make the button show up. Even though I'm using the exact same code as the documentation:

<AppleAuthentication.AppleAuthenticationButton   buttonType={     AppleAuthentication.AppleAuthenticationButtonType.SIGN_IN   }   buttonStyle={     AppleAuthentication.AppleAuthenticationButtonStyle.BLACK   }   cornerRadius={5}   onPress={() => {   }} />

It's worth noticing that the call to AppleAuthentication.isAvailableAsync() returns true.

I'm testing it in a Simulator. Is it not supposed to work in a dev environment? how am I supposed to test it then?
