How to use the gui/GuiSculptingTools.show function in gui

// sculpt tool
    var optTools = [];
    for (var i = 0, nbTools = Tools.length; i < nbTools; ++i) {
      if (Tools[i]) optTools[i] = TR(Tools[i].uiName);
    }
    this._ctrlSculpt = menu.addCombobox(TR('sculptTool'), this._sculptManager.getToolIndex(), this.onChangeTool.bind(this), optTools);

    GuiSculptingTools.initGuiTools(this._sculptManager, this._menu, this._main);

    this._ctrlTitleCommon = menu.addTitle(TR('sculptCommon'));
    // symmetry
    this._ctrlSymmetry = menu.addCheckbox(TR('sculptSymmetry'), this._sculptManager._symmetry, this.onSymmetryChange.bind(this));
    // continuous
    this._ctrlContinuous = menu.addCheckbox(TR('sculptContinuous'), this._sculptManager, '_continuous');

    GuiSculptingTools.show(this._sculptManager.getToolIndex());
    this.addEvents();
    this.onChangeTool(this._sculptManager.getToolIndex());
  }

onChangeTool(newValue) {
    GuiSculptingTools.hide(this._sculptManager.getToolIndex());
    this._sculptManager.setToolIndex(newValue);
    GuiSculptingTools.show(newValue);

    var showContinuous = this._sculptManager.canBeContinuous() === true;
    this._ctrlContinuous.setVisibility(showContinuous);

    var showSym = newValue !== Enums.Tools.TRANSFORM;
    this._ctrlSymmetry.setVisibility(showSym);

    this._ctrlTitleCommon.setVisibility(showContinuous || showSym);

    this._main.getPicking().updateLocalAndWorldRadius2();
  }
