Verifying NewPDFReaderWebView2List Policy

[nagneo]

Hello,

I'm developing a WPF application that utilizes WebView2 to display PDF files.
I'm seeking a method to verify whether the NewPDFReaderWebView2List policy has been applied.
I'm curious about any distinctions in user interface when the new PDF engine powered by Acrobat Reader is employed.

Environment:
.NET Framework 4.6.2
Microsoft Edge for Business 128
Microsoft.Web.WebView2 NuGet package 1.0.2651.64

Problem:
Intermittently, I've encountered vulnerability issues with Acrobat Reader when embedding it using the WinFormHost control.
I need to assess the possibility of the new PDF engine in WebView2 triggering similar problems.
