VSCode opens a page of content in an editor tab next to what you are doing. That’s pretty much as unobtrusive as it gets. You can just close it and move on. It’s just there if you want to and is a nice way to signal that it did indeed update as everything is pretty much automatic. Also it’s very easy to reopen later which was the OP complaint against popups. Now that I think about it, VSCode is pretty much best in class when it comes to update content notifications.
