launch window in a document based SwiftUI app for macOS

In my document based SwiftUI app for macOS, I'd like to show a window when the app is launched - showing, among other things, recently opened documents. Very much like Xcode.

I am not sure if this is possible. If it is, I like some pointers on how I can implement this window in my app.
