Can you mix Electron with native GUI?


Assuming I only want to target macOS, is there any way to have an Electron app and mix it with a native GUI?

Like e.g. have an Electron window and a palette window next to it with native UI.
Has anyone experimented with two apps that run alongside and communicate over XPC?

What I’m really looking for is a WebView like WKWebView that’s based on Chromium that I can bundle with my app. Is there anyone pursuing something like this?

I don’t expect any of this to exist but I want to make sure I’m not missing anything.
