How to access Chord Symbols at a cursor?

I'm trying to access Chord Symbols I've inserted in a staff, but the element.type can't show it, this is my code.
import QtQuick 2.2
import MuseScore 3.0

MuseScore {
version: "3.0"
description: qsTr("This plugin prints chord symbols in the selection")
menuPath: "Plugins.Notes.Print Chord Symbols"

  function accessChordSymbols() {
        var cursor = curScore.newCursor();
        cursor.rewind(0); 

        while (cursor.segment) {
              var element = cursor.element;
              console.log(element.type);
              cursor.next(); 
        }
  }

  onRun: {
        accessChordSymbols();
        Qt.quit();
  }

}
I got the message: Running…

As I know, 93 is chord object, 25 is rest object, there is no harmony object.
