Async/Await in Delphi

Let’s assume you’ve inherited this pretty useless code.
procedure TForm125.Button1Click(Sender: TObject);
var
  button: TButton;
begin
  button := Sender as TButton;
  button.Caption := 'Working ...';
  button.Enabled := false;
  Sleep(5000);
  button.Enabled := true;
  button.Caption := 'Done!';
end;

Now, your boss says, you have to make it parallel so the user can start three copies of it. (You also have to add two new buttons to the form to start those instances but that’s easy to do.)
