I am Developing a Custom Browser For Using VS 2022 WinForm With WebView2
I need To Add Unpacked Browser Extension.

Coded

Error I am Getting

System.Runtime.InteropServices.COMException
  HResult=0x80070032
  Message=The request is not supported. (0x80070032)
  Source=Microsoft.Web.WebView2.Core
  StackTrace:
   at Microsoft.Web.WebView2.Core.CoreWebView2Profile.<AddBrowserExtensionAsync>d__63.MoveNext()

  This exception was originally thrown at this call stack:
    Microsoft.Web.WebView2.Core.CoreWebView2Profile.AddBrowserExtensionAsync(string)

Any Solution Will Be Thanked.
