@mehdok Is there any way I can change the notification message in callback?

@dacianf There should be a way, but I couldn't make it work. I tried, but I couldn't get access to the plugin inside callback. We have a wiki page for how to access other plugins inside callback, but we are using the same plugin and it is really weird and it didn't worked;
