How does google-api work in offline request with tokens

My first problem is that when I make instance of the Google_Client and set all the needed scopes, configs, access types and others and then generate a URL for the user to AUTH with $client->createAuthUrl(); I allow access to my application with the google account that I'm logged. Everything works fine until I need to refresh the token.

I explain below about the token refresh.

  $this->client = new Google_Client();
            $this->client->setAuthConfig(Storage::path('secret.json'));
            $this->client->setAccessType("offline");        // offline access
            $this->client->setIncludeGrantedScopes(true);   // incremental auth
            $this->client->addScope(Google_Service_Drive::DRIVE_METADATA_READONLY);
            $this->client->setRedirectUri(env('APP_URL') . '/login/google/callback');

So the next thing I did is to get the google user data with laravel-socialite. This is the data I get:

The code for the request

  public function redirectToGoogleProvider()
    {
        $parameters = ['access_type' => 'offline'];

        return Socialite::driver('google')
            ->scopes(["https://www.googleapis.com/auth/drive"])
            ->with($parameters)
            ->redirect();
    }

There is no refresh token here. I assume that this is because of the way that google works in offline mode

After a user grants offline access to the requested scopes, you can continue to use the API client to access Google APIs on the user's behalf when the user is offline. The client object will refresh the access token as needed.

So I set the token that I get from the request and store in the database to the Google_Client instance with

$client->setAccessToken(Auth::user()->getUserInfo()->refresh_token)

This works. But when the token needs to be refreshed It's not getting refreshed. Instead I'm getting

"Invalid creditianals error".

Google says that:

"The client object will refresh the access token as needed." But this is not happening.

I don't understand If I need to call a special method or how does the Google_Client handle the token refresh.

I've tried using the CODE parameter to fetch the token and refresh token with it.

$client->fetchAccessTokenWithAuthCode($code);

And got this error:

array:2 [▼
  "error" => "invalid_request"
  "error_description" => "Could not determine client ID from request."
]

I'm probably not doing something right but I have no clue what. I'm confused to be honest. Already lost a day on this without any success.
