Adding favicon to application

Is there an easier way to add a favicon to the application than described here HTML5: Custom Favicon in HTML5?

Would it be possible to add it to the CustomAssetsConfig section in the appsettings.json file?

Interestingly, the favicon is mentioned in this article - Oidc redirect uri behavior. But the FaviconLogoUrl attribute mentioned in HOWTOSTART.md isn’t in the appsettings.json documentation or template.
