How do I obtain the DesktopSiteBridge object in an instance of the WinUI 3 Window class?

-------------------------------

如何获取 WinUI 3 Window 类实例下的 DesktopSiteBridge 对象？

WinUI 3 的 Window 类的实例是对 DesktopWindowXamlSource 创建窗口的一个高级包装，如何在 Window 类实例中获取 DesktoSiteBridge 对象？我在 WinUI 3 源代码中发现了 IContentIslandPartner 接口，通过这个接口可以把 ContentIsland 对象转换为 DesktopSiteBridge 对象，请问一下这个接口该怎么实现呢？

-------------------------------

The Window class instance of WinUI 3 is a high-level wrapper for the DesktopWindowXamlSource creation Window. How to obtain the DesktoSiteBridge object in the Window class instance? I found IContentIslandPartner interface in WinUI 3 source code, through which ContentIsland object can be converted to DesktopSiteBridge object, may I ask how to implement this interface?
