Is there any way to code via Extendscript "Make Compound Shape"?

Question

Hey there Adobe Community,
tl;dr - How do you get ExtendScript to call "Make Compound Shape". It's to make comic book word bubbles.
Full version:
I'm trying to create a script that would create a word bubble based on a single line. The intended use should speed up the comic book lettering process. For this particular iteration, I'm trying to grab the pathPoints of one line, and use that to create the word bubble. However, I was really hoping to find a way to execute the code to "Make Compound Shape", so I can modify the balloon tail later, ie - non-destructive.
Here's what I have so far.  Thanks to everyone in advance!

if ( app.documents.length > 0 ) {     var doc = app.activeDocument;     var artLayer = doc.layers[0];     // CURRENT ITERATION: Find the one and only line, and extract it's begin and end point.     var pointEnd = doc.pathItems[0].pathPoints[1].anchor;     $.writeln("pointEnd" + pointEnd + "\n");     var pointBegin = doc.pathItems[0].pathPoints[0].anchor;     $.writeln("pointBegin = " + pointBegin + "\n");     //CREATE ELLIPSE     var ellipse = artLayer.pathItems.ellipse(pointBegin[1], pointBegin[0], 225.0, 225.0, false, true ); //([top] [,left] [,width] [,height] [,reversed] [,inscribed])     ellipse.stroked = true;         var data = {             "anchors": [                 [pointEnd[0]+2, pointEnd[1]+2],                 [pointBegin[0], pointBegin[1]],                 [pointEnd[0]-2, pointEnd[1]-2]             ]     }        // CREATE BALLOON TAIL     var linez = doc.pathItems.add();     linez.stroked = true;    // loop thru the data.anchors     for(var i in data.anchors){         var point = linez.pathPoints.add();        point.anchor = data.anchors[i];        // if it's not the first or the last...whatever, it's only 3 points, so just say 2        //if((i != data.anchors.length - 1)&& i!=0)        if(i == 2){             point.rightDirection = [pointBegin[0]+2, pointBegin[1]-2];             alert("rightDirection: " + point.rightDirection);             point.leftDirection = [pointBegin[0]+2, pointBegin[1]-2]; //data.anchors[i];             alert("leftDirection: " + point.leftDirection);         } else {             point.rightDirection = data.anchors[i];             point.leftDirection = data.anchors[i];         }     }     ellipse.selected = true;     linez.selected = true;     //NEED HELP HERE!!! How do I call     //app.executeMenuCommand ("makeCompoundShape"); }

Great question, Monika.
I was looking to create one with where the balloon tail is angled at the top or bottom, depending on how the initial path is drawn.
In later iterations, the balloon size would be generated based on the text going into it. I have already written code that pulls the dialogue into Illustrator. The hope was I could pull it directly into the word bubble. Specifically, a rounded balloon tail, angled up or down, with a round word bubble that's been 'scrunched' for lack of a better term. It should look something like the following examples:
