INVISIBLE PLUGIN

hello we are creating a very simple plugin that when I write / invis become invisible when the rewrite disable invisibility effect so far I wrote this

PHP:

<?php
namespace invisible;

use pocketmine\plugin\PluginBase;
use pocketmine\utils\TextFormat;
use pocketmine\command\ConsoleCommandSender;
use pocketmine\event\Listener;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;

class main extends PluginBase implements Listener
{
public function onEnable()
{
    $this->getlogger()->info(TextFormat::GREEN .  "Il plugin è partito");
    $this->saveDefaultConfig();
}   
public function onDisable(){
    $this->getLogger()->info(TextFormat::RED . "Il plugin è spento");
}
public function onCommand(CommandSender $sender, Command $command, $label, array $args)
{
    if (! $sender->isOp ()) {
        $sender->sendMessage ( "Non sei op" );
        return;
    }
    if(strtolower($command->$getName())== "invis"){
       
        $command= str_replace("{player}", $player->getName(), $this->getConfig()->get("Comando"));
           
        $this->getServer()->dispatchCommand(new ConsoleCommandSender(), $command);
    }
}
}
?>

Um, EssentialsPE already has the invisible feature....

Also, please, some grammar and spelling correction?

but is not active essentials invisible effect.
apologize for my English but do not know much

EssentialsPE invisible effect works, and is definitely active. It isn't broken.

Don't use dispatchCommand in plugins if it is not necessary. Actually you can just use $player->addEffect().
