This is also a module, but it is interactive. You can enable/disable this module by typing
y!config edit levelEnable <true/false>
Yuki shouldn't sends the notifications in the general chat first place?! You can edit this as well, anyway you can enable or edit this module by typing
y!config edit levelChannel <yourchannelname/yourchannelid>
This module is not ready yet, so this page is gonna update if there any module about this, or exists in Yuki.
