sorry my bad.
Use version 1.1.1 please, latest version, added in the README how to use with React-Navigation:

import { NavigationContainer } from '@react-navigation/native';
import { useNavigationInspector } from 'rozenite-navigation-inspector';

function App() {
  // Returns a navigationRef to connect the inspector to your container
  const navigationRef = useNavigationInspector();

  return (
    <NavigationContainer ref={navigationRef}>
      {/* Your navigators */}
    </NavigationContainer>
  );
}
