Make player look at position

I made an AimBot command for fun, and I made a repeating task for the sender to look at the other player, here is my code:

PHP:

case "aimbot":
            if($sender->getName() == "coEthaniccc" or $sender->getName() == "Epicthic" or $sender->getName() == "WillamLin1128"){
                if(!isset($this->aimbot[$sender->getName()])){
                    $sender->sendMessage(TextFormat::BOLD . TextFormat::RED . "This is a test and should not be abused!");
                    $this->aimbot[$sender->getName()] = $sender->getName();
                    $this->getScheduler()->scheduleRepeatingTask(new ClosureTask(function (int $currentTick) use($sender) : void{
                        if(isset($this->aimbot[$sender->getName()])){
                            foreach($this->getServer()->getOnlinePlayers() as $player){
                                if($player->getX() - $sender->getX() <= 10 and $player->getX() - $sender->getX() >= -10 or $player->getZ() - $sender->getZ() <= 10 and $player->getZ() - $sender->getZ() >= -10){
                                    if($player->getPosition() !== $sender->getPosition()){
                                        $sender->lookAt($player->getPosition());
                                    }
                                }
                            }
                        }
                    }), 1);
                } else {
                    $sender->sendMessage(TextFormat::BOLD . TextFormat::GREEN . "Aimbot has been disabled!");
                    unset($this->aimbot[$sender->getName()]);
                }
            } else {
                $player->sendMessage(TextFormat::BOLD . TextFormat::RED . "You don't have permission to use this command!");
            }
            return true;
            break;

I think you can't use lookAt for a player, is there any alternative?
Thanks in advance!

P.S: If you find an error with my code, please tell me
