Editing the default kick message

I've wanted to edit this anticheat plugin but am looking for a way to change the default kick message. I know I've asked a question like this before, but am still having trouble. I would like to completely remove the "kicked by admin. reason:" text and customize it as my own. Thanks for the help.

PHP:

 if ($obs->Player != null && $obs->Player->isOnline())
      {
        $obs->Player->kick(TextFormat::ESCAPE."$cl" . $obs->KickMessage);
        if($this->plugin->getConfig()->get("KickPlayerMessageBool"))
        {
          $msg = $this->plugin->getConfig()->get("KickPlayerMessage");
          $smsg = $obs->ScanMessage($msg);
          $this->plugin->getServer()->broadcastMessage(TextFormat::ESCAPE."$cl" . $smsg);

 

Code:

$obs->player->kick("Oof to him", false);
