[API] how to group faces through the API?

Hi everyone!
With the ProBuilder API, I need to do the same operation as a "group selected faces" in the UV editor.
Is it possible? I couldn't find anything in the API doc.

 

Looking at the ProBuilder source code from the package, in the

AutoUVEditor.cs

file, I see this:

Code (csharp):

1.             if (GUILayout.Button(gc_GroupSelected))
2.             {
3.                 for (int i = 0; i < selection.Length; i++)
4.                     TextureGroupSelectedFaces(selection[i]);
5.  
6.                 ProBuilderEditor.Refresh();
7.             }

I would start there, and dig into:

Code (csharp):

1.         private static void TextureGroupSelectedFaces(ProBuilderMesh pb)//, pb_Face face)
2.  

 

Thanks, will try!
