Nice component! I like how it’s implemented close to where the share buttons are. Agree that we should integrate this into core and the android banner.
I have an old unimplemented mockup from a while ago that might address some thoughts mentioned here:
The idea with the text here 
was to have some sort of clear “what’s in it for me” — and literally show the site logo in an app-like way to make it a little clearer what this is all about.
That was mocked up for Android, which makes things easier because you can include a button that directly adds the PWA to your device.
Unfortunately iOS still requires you to go through their share sheet to get to this action… but I think we can have a button that triggers the share options? (we already do this for clicking the share icon on posts in iOS…)
组件很棒！我喜欢它在分享按钮附近实现的方式。同意我们应该将其集成到核心功能和 Android 横幅中。
我有一个很久以前未实现的旧模型，可能可以解决这里提到的一些想法：
这里 的文字想法是提供一种清晰的“对我有什么好处”——并以类似应用程序的方式实际显示网站徽标，以更清楚地说明这一切的意义。
那是为 Android 设计的，这使得事情更容易，因为您可以包含一个直接将 PWA 添加到您设备的按钮。
不幸的是，iOS 仍然需要您通过其共享表单才能执行此操作……但我认为我们可以有一个触发共享选项的按钮？（我们已经在 iOS 上点击帖子上的分享图标时这样做了……）
