Executing command AS player

How can I make a player execute a command using PlayerInteractEvent when tapping an iron ingot on the floor?

 

Code:

Server::dispatchCommand(CommandSender $sender, string $commandLabel)

 

Can you provide more specific? Like example of actual code

 

PHP:

public function onUseItem(PlayerInteractEvent $event){
  $player = $event->getPlayer();
  $item = $event->getItem();

  if($item->getId() == 256){
    $this->getServer()->dispatchCommand($player, "command");
  }
}


is it right ?

 

This will execute a command named 'Kohi' on the player interact?

PHP:

elseif ($item->getName() == C::BOLD . C::GREEN . "Kohi"){
       $this->MainItems($player);
       $this->getServer()->dispatchCommand($player, "kohi");
        }
