Hello everyone I have trouble using google authentification with firebase and expo go.

I applied this code so that I can make google authentification work:

import * as React from 'react'
import * as WebBrowser from 'expo-web-browser'
import { ResponseType } from 'expo-auth-session'
import * as Google from 'expo-auth-session/providers/google'
import { initializeApp } from 'firebase/app'
import {
  getAuth,
  GoogleAuthProvider,
  signInWithCredential,
} from 'firebase/auth'
import { Button } from 'react-native'

// Initialize Firebase
initializeApp({
})

WebBrowser.maybeCompleteAuthSession()

export default function App() {
  const [request, response, promptAsync] = Google.useIdTokenAuthRequest({
    clientId:
      'myclicentid.apps.googleusercontent.com',
  })

  React.useEffect(() => {
    if (response?.type === 'success') {
      const { id_token } = response.params

      const auth = getAuth()
      const provider = new GoogleAuthProvider()
      const credential = provider.credential(id_token)
      signInWithCredential(auth, credential)
    }
  }, [response])

  return (
    <Button
      disabled={!request}
      title="Login"
      onPress={() => {
        promptAsync()
      }}
    />
  )
}

But I keep having the following error:

TypeError: provider.credential is not a function. (In 'provider.credential(id_token)', 'provider.credential' is undefined)

What did I do wrong? Can someone help?
