Don't receive the access Token.

Hi, i'm using the library. I'm trying to the authorizeAndExchangeCode, but the function return me only the idToken.
I need the accessToken but it is null.

`final AuthorizationTokenResponse? result =
          await _appAuth.authorizeAndExchangeCode(
        AuthorizationTokenRequest(_clientId, _redirectUrl,
            serviceConfiguration: _serviceConfiguration,
            scopes: _scopes,
            promptValues: ['login']),
      );
      print("${result?.idToken}");
      print("ACCESS TOKEN: ${result!.accessToken}");

      if (result != null) {
        _processAuthTokenResponse(result);
        // await _testApi(result);
      }
    } catch (_) {
      _clearBusyState();
    }
  }`
  

Someone had the same problem? How i can resolve?

Start by reproducing the call to authorizeAndExchangeCode with the shown AuthorizationTokenRequest, including serviceConfiguration and scopes, and inspect the returned AuthorizationTokenResponse fields. Compare the idToken and accessToken values with the reported result; done means the expected accessToken behavior is documented or the issue is narrowed to a specific configuration or platform.
