Message Board Notification in Live Notifications Ajax plugin.

Does anyone help me please?
I want to have Message Board Notifications in Live Notifications Ajax plugin ( http://community.elgg.org/plugins/1144603/1.8.0/new-live-notifications-ajax ) when someone post in your message board plugin but i still haven't found out how to do this :(

In the plugin page, Fernando Vega said that: "

To integrate a new event this plugin manually:

It is only necessary to call the function add_new_notification() with appropriate parameters, this would be called into elgg action where running the desired event.

add_new_notification($to_user_guid, $from_user_guid, $action_type, $entity_guid, $description);"

Is this function used to add a new notification type? Where should i call it?

Thank you very much.
PS: I'm sorry if i had any typing mistakes cause i'm not speaking English.
