Cooldown to kit UI

hey , i created a plugin kit UI , i want to set a cooldown but i do not know how to do it, can you help me?

 

PHP:

case "hkit":
            $api = $this->getServer()->getPluginManager()->getPlugin("FormAPI");
            $ui = $api->createSimpleForm(function (Player $p, $data){
                $res = $data;
                
                switch($res){
                    case 0:
                    $p->getInventory()->addItem(Item::get(306, 0, 1));
                    $p->getInventory()->addItem(Item::get(307, 0, 1));
                    $p->getInventory()->addItem(Item::get(308, 0, 1));
                    $p->getInventory()->addItem(Item::get(309, 0, 1));
                    break;
                }
            });
            $ui->setTitle("Hyru-Kit");
            $ui->setContent("Kit de base");
            $ui->addButton("Kit 1", 0);
            $ui->sendToPlayer($p);
            break;
        }
        return true;
    }

 

I would like to put the cooldown here

 

save time using function time() or microtime(true) and then just check if it's bigger than you want

PHP:

public const KIT_DELAY = 60*5; // 60 sec * 5 -> 5 minutes
public $time = [];

function selectKit(Player $p) {
    if(isset($this->time[$p->getName()]) && time()-$this->time[$p->getName()] < self::KIT_DELAY) {
       $p->sendMessage("Please, wait");
        return;
    }
    $this->time[$p->getName()] = time();
}
