Mate desktop notification timeout is annoyingly long and unconfigurable

Is there any way to configure timeout of notification popoup? It's too long displaying on screen. While I'm collaborating with people there are many notification pop-ups bloating the display, and distracts me while waiting for popups go away by itself.

If I can configure timeout with any way right now, it would be nice. It's really urgent for me, because I'm dealing with this situation for a while and it's making me too uncomfortable.

Expected behaviour

Display timeout could be configurable.

Actual behaviour

Unconfigurable and very long timeout to display

Steps to reproduce the behaviour

Open "notification settings" app and see there is no timeout configuration, Also can be test how long the notification timeout period
