Elm couldn't find popup download button

[birdywen]

Hi Dear Gintaras,

The line 22, Elm couldn't find the download button after waiting. 

Please help!

Besides, the chrome waiting function is still very reliable after more thousands of testing and never failed. 
one question, If I use invoke or web-invoke to click links on the chrome page(w), will be all the page wait until loaded or just the main page (p.open(url)) ?  Thanks
 

Code:

// script "Notes-box.com.cs"
//.
script.setup(trayIcon: true, sleepExit: true, exitKey: KKey.MediaStop, pauseKey: KKey.MediaPlayPause);
//..

var w = wnd.find(0, "* - Google Chrome", "Chrome_WidgetWin_1");
var p = new ChromePage(w);

p.Open("https://notes-box.com/notes/classical-music/");
200.ms();
for (int i = 1; i < 83; i++) {
    p.Open($"https://notes-box.com/notes/classical-music/?PAGEN_1={i}");
    foreach (var song in w.Elm["web:IMAGE", prop: "@loading=lazy"].FindAll().Select(o => o.Navigate("pa").Value).ToArray()) {
        p.Open(song);
        200.ms();
        var composer = w.Elm["web:LINK", prop: "@ru=Классческая", navig: "pr la"].Find(1).Name;
        var download = $@"C:\notes-box\classical\{composer}";
        //filesystem.delete(download);
        filesystem.createDirectory(download);
        var click = w.Elm["web:GROUPING", prop: "@target=_blank"].Find(1);
        click.Invoke();
        100.ms();
        var button = w.Elm["web:LINK", "DOWNLOAD FILE", new("@href=/upload/iblock/*.pdf\n", "@target=_blank")].Find(18);
        //16.s();
        200.ms();
        button.Focus();
        keys.send("Apps");
        var w2 = wnd.find(5, "", "Chrome_WidgetWin_2","chrome.exe");
        var save = w2.Elm["MENUITEM", "Save link as…"].Find(3);
        save.Invoke();
        300.ms();
        var save1 = wnd.find(1, "另存为", "#32770");
        var input = w.Elm["TEXT", "文件名:", "class=Edit"].Find(1);
        input.SendKeys(download+input.Value);
        200.ms();
    
    script.debug();
    Debugger.Break();}
