AddHostObject HTML broken (not-implemented)?

[the-Arioch]

When i compile and run D:\DelphiLibs\WebView4Delphi\demos\Delphi_VCL\AddHostObject\AddHostObject.dpr the bottom frame says like "IP not found" and indeed the HTML says

    <script>
        //! Create IFrame from the parent html page and load it
        function createIFrame() {
            var i = document.createElement("iframe");
            i.src = "https://appassets.example/ScenarioAddHostObject.html";
            i.scrolling = "auto";
            i.frameborder = "0";

Yet the demo sources does not seem to add custom schema/domain filters for handling https://appassets.example/ nor is there any ScenarioAddHostObject.html in the D:\DelphiLibs\WebView4Delphi\assets\ folder

is there some abandoned feature, the test was intended to implement one day, but did not?

I see that Microsoft did some changes in the documentation about the ICoreWebView2.AddHostObjectToScript method recently.

That demo already had another issue with the "help wanted" label. I'll try to find some time to investigate this.

Well, the demo mostly works, albeit in some not the most intuitve way, but it worked for me with Win10 + Delphi 2007

except for the async method call, which was not designed to provide any visual feedback, so technically it probably worked too, just gave no clue to the observing user

then i was looking into the sources that maybe that async method call should've visible chanhe the iframe state - and got this. Probable reason is jsut you have all the necessary file in your working dir but jsut forgot to git add them, it happens :-)
