Laravel Socialite token refreshing

Here is the way I saving user from Socialite with offline access:

            $newUser                       = new User;            $newUser->name                 = $user->name;            $newUser->email                = $user->email;            $newUser->google_id            = $user->id;            $newUser->google_token         = $user->token;            $newUser->token_expires_at     = Carbon::now()->addSeconds($user->expiresIn);            $newUser->google_refresh_token = $user->refreshToken;            $newUser->avatar               = $user->avatar;            $newUser->avatar_original      = $user->avatar_original;            $newUser->save();

And here is my solution for token refreshing. I made it via creating accessor for token attribute in my User model:

    /**     * Accessor for google token of the user     * Need for token refreshing when it has expired     *     * @param $token     *     * @return string     */    public function getGoogleTokenAttribute( $token ) {        //Checking if the token has expired        if (Carbon::now()->gt(Carbon::parse($this->token_expires_at))) {            $url  = "https://www.googleapis.com/oauth2/v4/token";            $data = [                "client_id"     => config('services.google.client_id'),                "client_secret" => config('services.google.client_secret'),                "refresh_token" => $this->google_refresh_token,                "grant_type"    => 'refresh_token'            ];            $ch = curl_init($url);            curl_setopt($ch, CURLOPT_HTTPHEADER, ['Content-Type: application/x-www-form-urlencoded']);            curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");            curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);            curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));            curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);            $result = curl_exec($ch);            $err    = curl_error($ch);            curl_close($ch);            if ($err) {                return $token;            }            $result = json_decode($result, true);            $this->google_token     = isset($result['access_token']) ? $result['access_token'] : "need_to_refresh";            $this->token_expires_at = isset($result['expires_in']) ? Carbon::now()->addSeconds($result['expires_in']) : Carbon::now();            $this->save();            return $this->google_token;        }        return $token;    }

return Socialite::driver('google')    ->scopes()     ->with(["access_type" => "offline", "prompt" => "consent select_account"])    ->redirect();

By default refresh_token is returned only on first authorization, by adding "prompt" => "consent select_account" we force it to be returned every time.
