Hi,

I have manage to do the following:
1. Create an activity
2. Create a notification for that activity

I have used the following code as proof of concept:

add_action('bp_ready', function() {
    //1. Add an action
    $activity_id = bp_activity_add([
        'action' => '<b>HEJHEJHEJ</b>',
        'content' => '<b>my content my content my content my content my content my content</b>',
        'component' => 'groups',
        'type' => 'activity_update',
        'user_id' => get_current_user_id(),
    ]);

    //2. Send the notification
    if (bp_is_active('notifications')) {
        $activity = new BP_Activity_Activity($activity_id);
        $notification = bp_notifications_add_notification(array(
            'item_id' => $activity->id,
            'secondary_item_id' => $activity->user_id,
            'user_id' => $activity->user_id,
            'component_name' => buddypress()->activity->id,
            'component_action' => 'new_at_mention',
            'date_notified' => bp_core_current_time(),
            'is_new' => 1,
        ));
    }
});

So how do i make Buddypress to send an email to the user about that notification? Is there any tutorial that describes the process?
