    eventBus.on("element.contextmenu", event => {
      event.preventDefault();
      event.stopPropagation();

      const { element } = event;

      if (!contextPad._overlayId) {
        contextPad.open(element);
      } else {
        contextPad.close();
      }
    });

Is what I am doing in case anyone may be curious.
