How to use addWindow() ?

Hello guys!
Im trying to send the inventory of an chest to a player with addWindow() but its not working.
What do i wrong?

PHP:

public function onOpen(Player $player){
        $level = $player->getLevel();
        $level->setBlock(new Vector3($player->x, $player->y + 3, $player->z), Block::get(54));
        
        if($player->getLevel()->getTile(new Vector3($player->x, $player->y + 3, $player->z))){
            $chest = $player->getLevel()->getTile(new Vector3($player->x, $player->y + 3, $player->z));
            
        }
        $player->addWindow($chest->getInventory());
    }

 

sadly adding a chest inventory is harder then this , here are some source(s) that use this function and can help you , https://github.com/Muqsit/ChestShop/blob/master/src/ChestShop/Main.php#L141 , all credits to Muqsit for making this plugin i didn't make it!

 

When i use this, i need to right click 2 times

 

me to so your issue is?
