SwiftUI ShareLink doesn't show option "Copy" when sharing text

With a Button I can directly copy contents to the clipboard via UIPasteboard.general.setObjects(objects), but this is iOS-specific so I was hoping that ShareLink would allow me to share items in a platform-independent way. Is it possible to show a Copy item in the ShareLink sheet?

import SwiftUI

struct ContentView: View {
    let myType = MyType()
    
    var body: some View {
        ShareLink(item: myType, preview: SharePreview(myType.text))
    }
}

class MyType: Transferable {
    let text = "asdf"
    
    static var transferRepresentation: some TransferRepresentation {
        ProxyRepresentation { myType in
            return myType.text
        }
    }
    
}

#Preview {
    ContentView()
}
