Notification on New Database Row

[CoffeeLovesYou]

Hi,

I have a form set up to make a request. After a user makes a request, it then shows up on a table and our Mod views it.
However, how can I make a Notification appear on the notification list when there is a new request, aka a new row in the table?
I am using the Group Membership Requests modification, and all it has is 1 phrase and the rest is 1 plugin, which is using the hook notifications_list. Here is the only plugin.

PHP Code:

$requests = $vbulletin->db->query_read("
                SELECT COUNT(*) AS CountRequests, ".TABLE_PREFIX."usergrouprequest.usergroupid as GroupID, ".TABLE_PREFIX."usergroupleader.userid
                FROM ".TABLE_PREFIX."usergrouprequest
                                INNER JOIN ".TABLE_PREFIX."usergroupleader ON
                                (".TABLE_PREFIX."usergrouprequest.usergroupid = ".TABLE_PREFIX."usergroupleader.usergroupid)
                                WHERE ".TABLE_PREFIX."usergroupleader.userid= ".$vbulletin->userinfo['userid']."
                                GROUP BY GroupID
        ");

if ($vbulletin->db->num_rows($requests) == 1) {
  $request = $vbulletin->db->fetch_array($requests);
  $vbulletin->userinfo['groupmembership_requests'] = $request['CountRequests'];
  $groupurl = "joinrequests.php?usergroupid=".$request['GroupID'];
 }
else if ($vbulletin->db->num_rows($requests) > 1) {
  $vbulletin->userinfo['groupmembership_requests'] = 0;
  $count = $vbulletin->db->num_rows($requests);
  for ( ; $count > 0; $count-- ) {
   $request = $vbulletin->db->fetch_array($requests);
     $vbulletin->userinfo['groupmembership_requests'] += $request['CountRequests'];

  }
      $groupurl = "profile.php?do=editusergroups";
 } else {
  $groupurl = "profile.php?do=editusergroups";
  $vbulletin->userinfo['groupmembership_requests'] = 0;
 }
          

    $notifications['groupmembership_requests'] = array(
            'phrase' => $vbphrase['groupmembership_requests'],
            'link'   => $groupurl . $vbulletin->session->vars['sessionurl_q'],
            'order'  => 12); 


This mod basically, if you are a leader of a usergroup that has 1 or more join requests that need to be processed, you get a notification.
I want to modify it to give a notification when a new row is added to my table.
If anyone can guide me, please and Thank You!
