Overriding /help

i have made a customhelp GUI plugin and i want it to over ride the default /help command, right now it only shows the default help message when i type /help, but i know my plugin works because ive tried it with a different command

Here is what i have so far

PHP:

    public function onEnable()
    {
    if(!InvMenuHandler::isRegistered()){
        InvMenuHandler::register($this);
   }
 }

    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args) : bool{
        switch(strtolower($cmd->getName()))
        {
            case "help":

                    $warpmenu = InvMenu::create(InvMenu::TYPE_CHEST);

 

didnt work

 

Unregister the default help command and create your own

 

The help command is client side, the client will not send the command to server
