How to disable download protection

Hi there,

I'm using WPF Webview2 to render webpages. I would like to disable download protection feature in order to not show warning dialog when I download a harmful file (.eml file in my case).
I tried to add some additional browser arguments as bellow but it didn't work, the warning dialog is still displayed:
--disable-features=msSmartScreenProtection
--safebrowsing-disable-download-protection
--safebrowsing-disable-extension-blacklist

var coreViewOptions = new CoreWebView2EnvironmentOptions(
                "--disable-features=msSmartScreenProtection --safebrowsing-disable-download-protection --safebrowsing-disable-extension-blacklist", "de");

var webView2Environment = await CoreWebView2Environment.CreateAsync(null, null, coreViewOptions);

await webView.EnsureCoreWebView2Async(webView2Environment);

Are there any missing arguments? Or
Are there any other ways to disable download protection?

Thanks,
Huy
