Add custom Category Attribute to Category view on Front end

Question

I've created a module that adds a custom attribute for a category, Its a bolean that I will use to show/not show some text on frontend.

The attribute its being saved into the Database and I can get it and modify it in the backend, but I cannot get it in the frontend, I've really try many ways and nothing. Also when I do a Print_r of the category the attribute its not there.

I have some other files, but i Didnt add them for making the question not that long.This is what I have so far, please anyone can help me. Thanks

File: vendor/Module/Setup/InstallData.php

<?php

namespace vendor\module\Setup;

use Magento\Framework\Setup\{
    ModuleContextInterface,
    ModuleDataSetupInterface,
    InstallDataInterface
};

use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;

class InstallData implements InstallDataInterface
{
    private $eavSetupFactory;

    public function __construct(EavSetupFactory $eavSetupFactory) {
        $this->eavSetupFactory = $eavSetupFactory;
    }

    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
        $eavSetup->addAttribute(\Magento\Catalog\Model\Category::ENTITY, 'rr_show', [
            'type'     => 'int',
            'label'    => 'Desplegar Bloque RR',
            'input'    => 'boolean',
            'source'   => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
            'visible'  => true,
            'default'  => '1',
            'required' => false,
            'global'   => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_GLOBAL,
            'group'    => 'General Information',
            'sort_order' => 909,
        ]);
    }
}

    <group name="catalog_category">
        <attribute name="rr_show"/>
    </group>
</config>

File: vendor/module/view/frontend/templates/category.phtml

<?php

$isEnable = $block->getCurrentCategory()->getData('rr_show');
$isEnabletoString = $isEnable ? 'true' : 'false';
$categoryId = $block->getCurrentCategory()->getId();

print_r($categoryId);
?>
<?php 
<div isenable="<?=$isEnabletoString;?>"></div>
?>

This print_r show many attributes except mine, So this cageory.phtml its being called.

Thanks!

        'input' => 'select',
        'required' => false,
        'source' => 'Magento\Eav\Model\Entity\Attribute\Source\Boolean',
        'sort_order' => 110,
        'global' => \Magento\Eav\Model\Entity\Attribute\ScopedAttributeInterface::SCOPE_STORE,
        'group' => 'General Information',
        "default" => "",
        "class"    => "",
        "note"       => ""
]);
