Re-enable Notifications of Changes in Chat Status

I’m really enjoying Em Client’s unification of my email, chat, calendar and contact services from Google. One question: I found the popup notification of chat statuses annoying and turned them off via a config option on the popup itself. Now there’s someone I’m trying to intercept and want to turn them back on. Where can I re-enable this functionality?

this can be done in Tools - settings - general - notifications. There you can set all notifications available in eM Client
