Allow file explorer in Microsoft.Web.WebView2.WinForms.WebView2

Question

I have a Winforms app with a webview but the file explorer do not open when fired inside the webview (works fine on browser) i alredy tried the following :

Dim oEnvironment As Microsoft.Web.WebView2.Core.CoreWebView2Environment

Dim opts As CoreWebView2EnvironmentOptions = New CoreWebView2EnvironmentOptions()

'opts.AdditionalBrowserArguments = "--allow-file-access-from-files"
opts.AdditionalBrowserArguments = "--disable-web-security"

oEnvironment = Await Microsoft.Web.WebView2.Core.CoreWebView2Environment.CreateAsync(String.Empty, System.IO.Path.GetTempPath(), opts)

Await browser.EnsureCoreWebView2Async(environment:=oEnvironment)

The page do nor return any error.

How can i give permissions to open that?

Update:

I have a file picker like this below, if i drag and drop the files it works, if i click "Browse" nothing appen in the webview (on browser all woks fine)
