Adding window on play interact?

herro. How do I add a window on player interact\tap event?

PHP:

public function onTap(PlayerInteractEvent $event) {
        $player = $event->getPlayer();
        $item = $player->getInventory()->getItemInHand()->getId();
        if($item === 345){

            // popup a window/chest with some items
        }
}

 

you could at least try searching your question before posting...
