Accessing triangulation wave in ModifyContour triangulation=1

Hi. To create a Delaunay triangulation of a set of points, I followed the very useful tutorial in  https://www.wavemetrics.com/news/planar-triangulations. The documentation for ModifyContour states, "Like the contour lines, the triangulation is drawn using a graph trace, whose name is usually something like "contourInstanceName=triangulation"." Is it possible to get access to this wave? I can see it Modify Trace Appearance dialog, but I don't see how to access it.

OK, I found out how to do this. In case anyone else needs to do so, search for "Extracting Contour Trace Data" in Contour Plots.ihf.
