need runtime api of focus

[Cooooing]

Is your feature request related to a problem? Please describe.

我需要实现的功能是：在windows上，使用全局的快捷键唤起桌面程序或者失去焦点时隐藏。
快捷键唤起程序，我使用了 runtime.Show() ，但是显示的窗口并没有获得焦点。在使用上体验会不太好。
失去焦点时隐藏，我想在失去焦点时调用 runtime.Hide()，但是并没有监听失去焦点的事件。
我搜索了issus，在其中找到了 pull/1212，但是好像并没有得到我想要的效果。

Here is the translation（Machine translation, please forgive me）

The function I need to implement is to use global shortcut keys on Windows to wake up desktop programs or hide them when losing focus.

The shortcut key called up the program, and I used runtime. Show(), but the displayed window did not gain focus. The user experience may not be very good.

Hide when losing focus, I want to call runtime. Hide() when losing focus, but I did not listen for events that lose focus.

I searched issus and found [pull/1212] in it（ #1212 ）But it doesn't seem to have achieved the effect I wanted.

Describe the solution you'd like

我可能需要单独的 runtime api 或者 监听事件

I may need a separate runtime API or monitor events

It would be even better if we could focus on a specific element on the page
