How to use the scratch-blocks.VerticalFlyout function in scratch-blocks

ScratchBlocks.Blocks.sensing_touchingobjectmenu.init = function () {
        const mouse = ScratchBlocks.ScratchMsgs.translate('SENSING_TOUCHINGOBJECT_POINTER', 'mouse-pointer');
        const edge = ScratchBlocks.ScratchMsgs.translate('SENSING_TOUCHINGOBJECT_EDGE', 'edge');
        const json = jsonForMenuBlock('TOUCHINGOBJECTMENU', spriteMenu, sensingColors, [
            [mouse, '_mouse_'],
            [edge, '_edge_']

        this.jsonInit(json);
    };

    ScratchBlocks.Blocks.control_create_clone_of_menu.init = function () {
        const json = jsonForMenuBlock('CLONE_OPTION', cloneMenu, controlColors, []);
        this.jsonInit(json);
    };

    ScratchBlocks.VerticalFlyout.getCheckboxState = function (blockId) {
        const monitoredBlock = vm.runtime.monitorBlocks._blocks[blockId];

            return ScratchBlocks.StatusButtonState.READY;
        }
        return ScratchBlocks.StatusButtonState.NOT_READY;
    };

    ScratchBlocks.FieldNote.playNote_ = function (noteNum, extensionId) {
        vm.runtime.emit('PLAY_NOTE', noteNum, extensionId);
    };
