Titles and Sound not working on delay task

When I put a title message and sound on a delay task (from join) it does not display and it shows no errors, why is this??

PHP:

<?php
namespace basprohop\JoinEvent;
use pocketmine\Player;
use pocketmine\Server;
use pocketmine\utils\TextFormat;
use pocketmine\scheduler\PluginTask;
use basprohop\CombinedSlots;
use pocketmine\math\Vector3;
use pocketmine\level\sound\LaunchSound;
class ShowTask extends PluginTask {
    /** @var Player */
    private $player;
   
    public function __construct($plugin, Player $player) {
    parent::__construct($plugin);
    $this->player = $player;
    }

    public function onRun($currentTick) {
        $this->player->addTitle("#bla#nk#", "", 5, 80, 20);
        $level = $this->player->getLevel();
        $level->addSound(new LaunchSound(new Vector3(49, 45, -890)));
        return true;
    }
}

 

add pocketmine\level\Level?
and what is $plugin on __construct?

 

How long is the task delayed?
Why is your constructor not compatible with PluginTask ?
Why are you passing Player objects to a task?
Are you certain you scheduled the task properly?

 

PHP:

public function onRun(int $currentTick){}

Add int before $currentTick
