How can I use this React Native PGP library?

I want to make a App that just generates a PGP Keypair and Displays it in those with useState but i didn't unterstand anything on the Documentation https://github.com/jerson/react-native-fast-openpgp#readme :/ can someone help me ?

Just Generating, Encrypt/Decrypt would be a Project for later, Iam new to React Native and dont want to make it too complicated.

import { StatusBar } from 'expo-status-bar';import { useState } from 'react';import { StyleSheet, Text, View, Button } from 'react-native';export default function App() {const [MyPublicKey,setMyPublicKey] = useState('No key yet');const [MyPrivateKey,setMyPrivateKey] = useState('No key yet');const [ButtonText,setButtonText] = useState('Generate Keypair');const GenerateKeypair = ()=>{// This is an Example, Here Should be the Function from the LibrarysetMyPublicKey('-----BEGIN PGP PUBLIC KEY BLOCK-----')setMyPrivateKey('-----BEGIN PGP Private KEY BLOCK-----')setButtonText('renew')}return (<View style={styles.container}><Text>{MyPublicKey}</Text><Text>{MyPrivateKey}</Text><Button onPress={GenerateKeypair} title={ButtonText}/><StatusBar style="auto" /></View>  );}const styles = StyleSheet.create({container: {flex: 1,backgroundColor: '#fff',alignItems: 'center',justifyContent: 'space-evenly',  },});

I used openpgp library for normal react but with react native it doesnt workall i had to do is this :

const [MyPrivateKey,setMyPrivateKey] = useState('');   const [MyPublicKey,setMyPublicKey] = useState('');   const [MyRevocation,setMyRevocation] = useState('');   const GenerateKeypair = async () => {     const { privateKey, publicKey, revocationCertificate } = await generateKey({         type: 'ecc', // Type of the key, defaults to ECC curve: 'curve25519', // ECC curve name, defaults to curve25519 userIDs: [{ name: 'Jon Smith', email: 'jon@example.com' }], // you can pass multiple user IDs passphrase: 'super long and hard to guess secret', // protects the private key format: 'armored' // output key format, defaults to 'armored' (other options: 'binary' or 'object')     });     setMyPrivateKey(privateKey);     // '-----BEGIN PGP PRIVATE KEY BLOCK ... '     setMyPublicKey(publicKey);      // '-----BEGIN PGP PUBLIC KEY BLOCK ... '     setMyRevocation(revocationCertificate); // '-----BEGIN PGP PUBLIC KEY BLOCK ... ' }
