I'm looking to access to WebView2 of another process that uses WebView4Delphi () component. The goal is to fill the form loaded to its browser component and click a button.

For now I can only find the window that contains web page, but don't know how to get its WebView2 interface

        MainWindow := FindWindow('TFWebViewExplorer.UnicodeClass', nil);
        if MainWindow = 0 then
          Exit;
        LWnd := FindWindowEx(MainWindow, 0, 'TWVWindowParent', nil);
        if LWnd <> 0 then
          LWnd := FindWindowEx(LWnd, 0, 'Chrome_WidgetWin_0', nil);
        if LWnd <> 0 then
          LWnd := FindWindowEx(LWnd, 0, 'Chrome_WidgetWin_1', nil);
        if LWnd <> 0 then
          LWnd := FindWindowEx(LWnd, 0, 'Intermediate D3D Window', nil);

In case it will be possible to access TWVBrowserBase class from my program the idea is to run JavaScript using TWVBrowserBase.ExecuteScript().
