Solved adding a usage message on command

Hello, I have this code from a friend plugin which I'm trying to edit into a party plugin

PHP:

    public function onCommand(CommandSender $sender, Command $command, $label, array $args) : bool{
        switch($command->getName()){
            case "friend":
            if ($sender instanceof Player){
                if (isset($args[0])){
                    switch ($args[0]){
                        case "add":
                        if (isset($args[1])){
                            $player = $this->getServer()->getPlayer($args[1]);
                            if(!$player == null){
                                $this->addRequest($player, $sender);
                            }    else {
                                $sender->sendMessage("§c" . $args[1] . " §cis not online");
                            }
                        }else{
                            $sender->sendMessage("§eUsage: /friend add [name]");
                        }
                    break;
                    case "remove":
                        if (isset($args[1])){
                            if ($this->removeFriend($sender, $args[1])){
                                $sender->sendMessage("§c" . $args[1] . " §cremoved as your friend");
                            }else{
                                $sender->sendMessage("§cFriend not found do /friend list to list your friends");
                            }
                        }else{
                            $sender->sendMessage("§eUsage: /friend remove [name]");
                        }
                    break;
                    case "list":
                        $config = new Config($this->getDataFolder()."players/". strtolower($sender->getName()).".yml", Config::YAML);
                        $array = $config->get("friends", []);
                        $sender->sendMessage(TextFormat::GOLD.TextFormat::BOLD."Friends:");
                        foreach ($array as $friendname){
                            $sender->sendMessage(TextFormat::GREEN."* ".$friendname);
                        }
                    break;
                  
                }
            }}else{
        $sender->sendMessage("Must use command in-game");
    }
            break;
            case "accept":
                //echo var_dump($this->request);
                if (in_array($sender->getName(), $this->request)){
                    //echo "added";
                    foreach ($this->request as $target => $requestp){
                        $target = $this->getServer()->getPlayer($target);
                        $requestp = $this->getServer()->getPlayer($requestp);
                        echo $target->getName().$requestp->getName();
                        if ($requestp->getName() === $sender->getName()){
                            //echo "yes";
                            $this->addFriend($target, $requestp);
                            $this->addFriend($requestp, $target);
                        }
                      
                    }
                }else{
                    $sender->sendMessage("§cNo pending friend requests");
                }
        }
        return true;
    }

What I'm trying to do is add a usage message such as $sender->sendMessage("showing friend commands") when the player types /friend I don't know where it goes :/ help

 

PHP:

}}else{
$sender->(no pending)


Should be changed to

PHP:

}else{
    $sender->sendMessage(“Showing friend commands”);
}else{
... (no pending)


 

thanks
