V14: How to close notification manually?

I set setDuration(0) and I thought that the dialog would be closed at touch/click but it doesn’t and I can’t find a way add this behaviour.
I am trying to make a warning/error message that popup in the middle of the screen

UPDATE: do I have to add a component (button most likely) to achieve this? which will ruin aesthetic appearance of Notifications, why there is no listener for this?

solved: used Dialog instead, at least this can be closed touching around without having to add a button

It might be doable by some hack, but it looks like you can’t even add a click listener to the notification overlay itself through the Element API. There seems to be an open issue about this as well: https://github.com/vaadin/vaadin-notification/issues/120
