ToolbarItem in the macOS sidebar with Swift UI?

During the 10104 Session John explained that the item can be placed inside the sidebar by setting it to track the sidebarSeparator. Is this achievable in a Multiplatform Swift UI application?

I've tried all of the ToolbarItemPlacements available, but with no success.
Would love an answer to this as well!
As would I!
I'm waiting for that too :/
Unable to do this with MacOS alone it seems
I was able to do this NOT in SwiftUI but with AppKit finally haha. My issue was that isNavigational was enabled which cancels the functionality to have it be in the sidebar. Just use sidebarTrackingSeparatorItemIdentifier
Yes @neptunes, the way to make this happen with AppKit was explained during the session, but I'm curious if the SwiftUI solution exists.
