SwiftUI 2 collapse section headers by default

Is there a way to have the new List > Section collapsible headers be collapsed by default. I have a list section of upcoming events which should be shown but then I have another section of historical events which I would prefer to be collapsed by default.

The app is for iOS only so no APIs from Mac OS
I don’t think that is available in SwiftUI yet. They only come expanded by default so you will have to wait and see what iOS 15 brings us.
I wonder what Apple Swift developers think !

As of iOS 15 and Swift 5, the Previewer in Xcode shows a sectioned List with collapsable headers. These are even interact-able when running the preview live. However when deploying to the simulator, these collapsable headers do not function. So it seems this will be something available very soon.

Is there any way to hide these collapsible headers entirely. I know you can in macOS, but can't find out how to do in iOS?
