Capacitor app. Log in with aws amplify v6 via Google

Capacitor
1

I am building a mobile application from an Angular project using Ionic and capacitor. It is my first mobile application. I use AWS Amplify plugin to login to the app. Log in with email and password works well. I have an issue with log in with Google as a social provider.
When I call amplify/auth function authWithRedirect({provider: Google}) it redirects me to the Google to sign In. After I have finished Google registration I receive a popup which asks how I would like to open the application: using Browser or mobile application. I choose mobile app. it redirects me back to my app with a code in the url query. I should change this code to tokens. I use App.urlOpener to catch this redirect.

App.addListener('appUrlOpen', (event) => {
        this.zone.run(async() => {
          const urlToCatch = 'hellokaiio?code=';
          if (event.url.includes(urlToCatch )) {
              const {tokens} = await fetchAuthSession(); //AWS amplify function
          }
        });
    });
  }

But there are no tokens there. The authentication is not finished.
In my web application the behaviour is similar. But when Google redirects me back with a code, it also send a text/html response, which (I think) includes a next step to finish the authentication.
So, I can catch a google code from appUrlOpen event in my mobile app. But how can I change it to tokens?
There is my capacitor Config file:

import type { CapacitorConfig } from '@capacitor/cli';

const config: CapacitorConfig = {
  appId: 'com.hellokaiio.app',
  appName: 'Hellokaiio',
  webDir: 'www',
  server: {
    hostname: 'hellokaiio',
    androidScheme: 'https'
  }
};

export default config;

There is my AndroidManifest.xml file

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.hellokaiio.app">

  <application
    android:allowBackup="true"

    </provider>
  </application>

  <!-- Permissions -->

  <uses-permission android:name="android.permission.INTERNET" />
</manifest>

There is my aws amplify configuration file:

const redirectBaseURL = window.location.protocol + '//' + window.location.host;

const oauth = {
  domain: environment.authDomain,
  redirectSignIn: [redirectBaseURL],
  redirectSignOut: [redirectBaseURL + '/signout'],
  responseType: "code" as "code" | "token",
  scopes: ["email", "profile", "openid", "aws.cognito.signin.user.admin"]
};

Amplify.configure({
  Auth: {
    Cognito: {
      identityPoolId: '',
      userPoolId: environment.userPoolId,
      userPoolClientId: environment.userPoolWebClientId,
      loginWith: {
        oauth
      }
    }
  }
});

Please help me to log In correctly and to catch tokens.
