Solved how to add permission node for plugin

So i just made a simple plugin and it works. (added a command that does nothing) and it loads with no problems. but the permission node doesn't exist and i don't how to add it.
i used devtools to make the .phar file.

PHP:

<?php

namespace mmm545\MyPlugin;
 
use pocketmine\plugin\PluginBase;
use pocketmine\Server;
use pocketmine\Player;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\utils\TextFormat;

    class Main extends PluginBase{
        public function onCommand(CommandSender $sender, Command $command, string $label, array $args) : bool{
        switch($command->getName()){
            case "test":
                    //will add code later
            break;
        }
        return true;
    }
}

yml file:

Code:

name: MyPlugin
version: 1.0
main: mmm545\MyPlugin\Main
api: 3.11.5
commands:
 test:
  description: Just a test.
...

Add it to the plugin.yml like so:

Code:

name: MyPlugin
version: 1.0
main: mmm545\MyPlugin\Main
api: 3.11.5
commands:
 test:
  description: Just a test.
  permission: myplugin.test

permissions:
 myplugin:
  default: false
  children:
   myplugin.test:
    default: op

 

PHP:

if($sender->hasPermission("myplugin.test")){
    //add some thing here
}
