Considering the comments from [here](https://discourse.slicer.org/t/updated-sample-code-for-calling-cli-via-c/7840/4), I reduced the code as follows, but still the question remains: can I execute the scripted module based on the following code? How would I do that?

```auto
// get module and its widget
qSlicerScriptedLoadableModule* scrModule = static_cast<qSlicerScriptedLoadableModule*>(qSlicerCoreApplication::application()->moduleManager()->module("SurfaceToolbox"));
vtkSlicerScriptedLoadableModuleLogic* moduleLogic = vtkSlicerScriptedLoadableModuleLogic::SafeDownCast(scrModule->logic());

// create scripted module node
vtkMRMLScriptedModuleNode* scrNode = vtkMRMLScriptedModuleNode::SafeDownCast(scene->CreateNodeByClass("vtkMRMLScriptedModuleNode"));
scene->AddNode(scrNode);

// set parameters
scrNode->SetParameter("connectivity", "true");

// TBD: set input/output nodes
// TBD: start execution

```
