Change bookmark's icon in norton browser

Norton Private Browser: v152.0.35367.42 (Official Build)

Windows 11 Pro v25H2

Windows OS Build: 26200.9457

I just added a new bookmark to the browser’s bookmark bar. It is automatically using the web site’s FAVICON.ICO fo the icon. However, I have my own icon I would prefer to use. How can I change it to use my own icon file?

Thanx.
