Not able to access Customer Session via custom module in Magento 2

I’m not able to access the customer session in my custom module. However, when I’m navigating my custom action to salesrep/index/account I’m able to get the customer session. But when I’m navigating my custom module via category click not able to access it.

Here is my code.
Controller Code

<?php
namespace ABCSolutionsCustomerControllerIndex;

use MagentoFrameworkAppActionContext;
use MagentoFrameworkAppConfigScopeConfigInterface;
use MagentoFrameworkAppResponseInterface;
use MagentoFrameworkViewResultPageFactory;
use PsrLogLoggerInterface as Logger;

class Accounts extends MagentoFrameworkAppActionAction
{

    /**
     * @var PageFactory
     */
    protected $resultPageFactory;

    /**
     * Logger.
     *
     * @var Logger
     */
    protected $logger;

    /**
     * Core store config
     * @var ScopeConfigInterface
     */
    protected $_scopeConfig;

    /**
     * @param Context $context
     * @param PageFactory $pageFactory
     * @param ScopeConfigInterface $scopeConfigInterface
     * @param Logger $loggerInterface
     */
    public function __construct(
        Context $context,
        PageFactory $pageFactory,
        ScopeConfigInterface $scopeConfigInterface,
        Logger $loggerInterface,
    ){
        $this->resultPageFactory = $pageFactory;
        $this->_scopeConfig = $scopeConfigInterface;
        $this->logger = $loggerInterface;
        parent::__construct($context);
    }

    /**
     * @return ResponseInterface|MagentoFrameworkControllerResultInterface|MagentoFrameworkViewResultPage
     */
    public function execute()
    {
        $page = $this->resultPageFactory->create();
        $page->getConfig()->getTitle()->set(__('Customers'));
        return  $page;
    }


}

Block Code:

<?php
namespace ABCSolutionsCustomerBlock;

use MagentoFrameworkViewElementTemplate;
use MagentoFrameworkViewElementTemplateContext;
use MagentoCustomerModelSession as CustomerSession;


    class Accounts extends Template
    {
    
        /**
         * @var CustomerSession
         */
        protected $customerSession; 
    
        /**
         * @param Context $context
         * @param CustomerSession $customerSession
         */
        public function __construct(
            Context $context,
            CustomerSession $customerSession
        ){
            $this->customerSession = $customerSession;
            parent::__construct($context);
        }
        public function getCustomerId()
        {
            if ($this->customerSession->isLoggedIn()) {
                return $this->customerSession->getCustomer()->getId();
            }
            return 0;
        }
        }

Layout code

<referenceContainer name="content">
            <block class="ABCSolutionsCustomerBlockAccounts" name="sales_rep_accounts" template="ABCSolutions_Customer::accounts.phtml" cacheable="false" />
        </referenceContainer>

Phtml code:

<?php /** @var $block ABCSolutionsCustomerBlockAccounts */ ?>
    $customerId = $block->getCustomerId();

Static Block:

{{block class="ABCSolutionsCustomerBlockAccounts" template="ABCSolutions_Customer::accounts.phtml"}}

And the Category:
For this category there are no products, So when we click on this the custom module will show.

In frontend website menu.

Any help on this?
