How to click on handle Chrome's "save as" dialog using Java in LeanFT Tool?

Using LeanFT's Java SDK, is it possible to perform click operation on "Save" button from Chrome's "Save As" dialog?

String home = System.getenv("USERPROFILE") + "\\Downloads\\";
String fileName = "xxxxxxxxx.xls";
File file = new File(home + fileName);
if (file.exists()) {
   file.delete();
   System.out.println("Deleted existing CurrentSortRules.xls file if it is already present");
    }
    Window popup = Desktop.describe(Window.class, new WindowDescription.Builder().ownedWindow(false).childWindow(false)
                                .windowClassRegExp("Chrome_WidgetWin_1").windowTitleRegExp(" Google Chrome").build())
                .describe(Dialog.class, new DialogDescription.Builder().ownedWindow(true).childWindow(false)
                        .text("Save As").nativeClass("#32770").build());
