Solved InvMenu

How do I turn off getting items from the GUI in the InvMenu plugin?

 

I believe you are trying to cancel a transaction.
An example from InvMenu could work

PHP:

$menu->setListener(function(InvMenuTransaction $transaction) : InvMenuTransactionResult{
    if($transaction->getItemClicked()->getId() === ItemIds::APPLE){
        $player->sendMessage("You cannot take apples out of that inventory.");
        return $transaction->discard();
    }
    return $transaction->continue();
});

I want the GUI to be read only.
