@metamask/detect-provider: Unable to detect window.ethereum.

I'm building a hybrid app using Ionic.

When I serve the app in the browser (Chrome), it works fine asking for the Metamask authentication (opens Metamask as expected).

However when I build that for native Android (I'm using Capacitor), even though the app opens on my Android phone normally after I launch it from Android Studio, it does not ask me to authenticate with Metamask.

After doing some troubleshoot I attached to the app (via Chrome Device Inspect) running on my real phone which is plugged via USB in my computer, and this is what I get on the native app:

```

What should I do in order to have the native app being able to authenticate with the Metamask installed app?

Thanks!

Start with @metamask/detect-provider's window.ethereum detection and compare the browser environment with the Capacitor native Android WebView described in the report. Reproduce the null provider and determine whether this repository supports native-app provider detection; done should be a confirmed supported path or a clearly documented limitation.
