How to prevent the web page to read or write cookies in WebView2

Question

I'm trying to write to program with webview2, the control document is here:

https://learn.microsoft.com/en-us/microsoft-edge/webview2/

The WebView2.CoreWebView2.CookieManager provides lots of methods to read/write cookies, but this is not what I want.

I want to know when the webview2 web page reads/writes the cookies on my disk, or disable cookie read/write for specified site.

For example, I'm the user that use a program with webview2 to navigate www sites, and I know www.microsoft.com is friendly to me, so I allow this site to write/read cookies in my disk, so I add it into the whitelist. And I also know www.buygoodsfoo.com will peek what I had buy from internet through cookies, and may push ADs to me, so I won't let it read/write cookies on my disk, then I can add it in the blacklist.

So there is a requirements, that I need to prevents specified site to read/write cookes in webview2 program, or when the site attempt to read/write cookies, the object control could raise up an event, so I can write some code to do such work in the event callback, cancel it or pass it.

who can tell me the way?

Thanks very much.
