How can i get my plugin to integrate With EconomyAPI and also how would that work?

PHP:

<?php
namespace ShatteredGlassRP;
use pocketmine\Server;
use pocketmine\Player;
use pocketmine\command\Command;
use pocketmine\command\CommandSender;
use pocketmine\plugin\PluginBase;
use pocketmine\event\Listener;
class Main extends PluginBase implements Listener {
   
    public function onEnable()
    {
        $this->getServer()->getPluginManager()->registerEvents($this, $this);
    }
   
    public function onCommand(CommandSender $sender, Command $cmd, string $label, array $args): bool {
        switch(strtolower($cmd->getName())) {
           
            case "shatter":
                $sender->sendMessage("*Glass Breaks*");!
                return true;
            break;
           
            case "safecrack":
               
                $sender->sendMessage("*You cracked the safe!!!!!*");
                return true;
            break;
       
           
            case "lockpick":
               
                $sender->sendMessage("*You Picked The Lock!!!!*");
                return true;
            break;
           
        }
    }
   
    public function onDisable() {
    }
   
}
