I am using Magento 2.3

I have created the Custom extension for category attribute "Popular category" and I have installed this extension successfully but the issue is I have set the default value as 0 but when I saw the attribute in admin it is already selected.

Here are the extension files:

app/code/Custom/CategoryAttributes/Setup/InstallData.php

<?php


namespace RootwaysCategoryAttributesSetup;

use MagentoFrameworkSetupInstallDataInterface;
use MagentoFrameworkSetupModuleContextInterface;
use MagentoFrameworkSetupModuleDataSetupInterface;
use MagentoEavSetupEavSetup;
use MagentoEavSetupEavSetupFactory;
use MagentoCatalogModelCategory;
use MagentoEavModelEntityAttributeScopedAttributeInterface;

/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface

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

 /**
 *
 * @param EavSetupFactory $eavSetupFactory
 */
 public function __construct(EavSetupFactory $eavSetupFactory)
 
 $this->eavSetupFactory = $eavSetupFactory;
 

 public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
 
 /** @var EavSetup $eavSetup */
 $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);
 $eavSetup->addAttribute(
 Category::ENTITY,
 'popular_category',
 [
 'type' => 'int',
 'label' => 'Popular Category',
 'input' => 'select',
 'required' => false,
 'sort_order' => 100,
 'global' => ScopedAttributeInterface::SCOPE_STORE,
 'group' => 'General Information',
 'default' => 0,
 'visible_on_front' => true,
 ]
 );

Attribute in admin:

As you can see attribute is already selected to "Yes" but I want it to be selected as "No" by default. So, how can I achieve this?

And also I am not able to use this attribute in the front end. So, How can I do this?
