    GoogleOAuth2Module.registerAsync({
      imports: [ConfigModule],
      inject: [ConfigService],
      useFactory: (configService: ConfigService) => {
        return {
          clientId: configService.get('GOOGLE_CLIENT_ID'),
          clientSecret: configService.get('GOOGLE_SECRET'),

  ) {}
  public async googleOauth(data: { accessToken: string }) {
    const tokenInfo = await this.googleOAuth2Service.getTokenInfo(
      data.accessToken,
    );
    console.log(tokenInfo);
    const ticket = await this.googleOAuth2Service.verifyIdToken({
      idToken: data.accessToken,
      audience: this.configService.get('GOOGLE_CLIENT_ID'),
    });
