How to get all currency codes whether enabled or not in magento 2

Im trying to add custom atribute ‘currency codes’ by creating ‘Vendor/Module/Setup/Patch/Data/PriceCrncyCodeAttribute.php’.

declare(strict_types=1);

namespace VendorModuleSetupPatchData;

use MagentoEavModelEntityAttributeScopedAttributeInterface;
use MagentoEavSetupEavSetup;
use MagentoEavSetupEavSetupFactory;
use MagentoFrameworkSetupModuleDataSetupInterface;
use MagentoFrameworkSetupPatchDataPatchInterface;
use MagentoFrameworkSetupPatchPatchRevertableInterface;
use MagentoStoreModelStoreManagerInterface;
use MagentoFrameworkAppState;

class PriceCrncyCodeAttribute implements DataPatchInterface, PatchRevertableInterface
{

    /**

     */
    private $moduleDataSetup;
    /**
     * @var EavSetupFactory

    private $eavSetupFactory;

    private $storeManager;
    private $appState;

    /**

    ) {
        $this->moduleDataSetup = $moduleDataSetup;
        $this->eavSetupFactory = $eavSetupFactory;
        $this->storeManager = $storeManager;
        $this->appState = $appState;

    }

    /**

    {
        try {
            $this->appState->setAreaCode('adminhtml');
        } catch (LocalizedException $e) {
            // Area code is already set, so no action needed
        }

        $this->moduleDataSetup->getConnection()->startSetup();
        /** @var EavSetup $eavSetup */
        $eavSetup = $this->eavSetupFactory->create(['setup' => $this->moduleDataSetup]);

        $eavSetup->addAttribute(
