可根据开发者手册第279页的指引，在初始化PDFUI实例时，通过自定义createContextMenu方法，隐藏SDK内置的注释右键菜单，使其显示为浏览器默认菜单。具体实现可参考如下代码片段：

var pdfui = new UIExtension.PDFUI({
    viewerOptions: {
        libPath: '../../../lib',
        jr: {
            licenseSN: licenseSN,
            licenseKey: licenseKey
        },
        viewerUI: new class extends UIExtension.XViewerUI {
            createContextMenu(owner, anchor, config) {
                if (owner instanceof PDFViewCtrl.AnnotComponent) {
                    const contextMenuName = super.getAnnotsContextMenuName(owner)
                    // if (contextMenuName === 'fv--underline-contextmenu'){    //屏蔽指定注释的右键菜单项
                    if (contextMenuName){   //屏蔽所有注释的右键菜单项
                        return;
                    }
                }
                return super.createContextMenu(owner, anchor, config);
            }
        }()
    },
    renderTo: '#pdf-ui',
    appearance: UIExtension.appearances.adaptive,
    fragments: [],
    addons: UIExtension.PDFViewCtrl.DeviceInfo.isMobile ?
        '../../../lib/uix-addons/allInOne.mobile.js' : '../../../lib/uix-addons/allInOne.js'
});
