How can I remove selected sections? [js][CC2014]

Question

Hello,
I'm trying to remove selected sections from my document.
I figured out how to remove them by index number like this:
var myDoc = app.activeDocument;
var mySections = myDoc.sections;
mySections[1].remove();
When I try to limit the removal of sections to just my selection, I keep getting errors. I've tried:
var myDoc = app.activeDocument;
var mySections = myDoc.sections;
var mySelection = myDoc.selection;
mySelection.sections[1].remove();
And:
var myDoc = app.activeDocument;
var mySections = myDoc.sections;
var mySelection = myDoc.selection;
mySelection[0].sections[1].remove();
But I keep getting Error 21 undefined is not an object on line 5.
Any help is much appreciated.

I'm trying to remove the section not the content. It would be the equivalent of selecting the first page of a section in the page panel, then right-clicking on it and clicking on "Numbering and sections..." and then unchecking the "Start Section" checkbox.
That's what the first code snippet does. But I was only able to do it by index number.
I've read in other posts that it's difficult to specify selections in the page panel using scripting. I'm not sure if it's even possible.
