CI4 libaries function call in VIEW

Hello Everyone,

I am using CI 4.0.4
XAMPP CONTROL 3.2.4

I AM USING CI 4.0.4 FOR MY ONGOING LIVE PROJECT

CURRENTLY I AM FACING SOME ISSUE

I HAVE CREATED LIBRARIES

Code:

<?php
namespace App\Libraries;
use CodeIgniter\HTTP\RequestInterface;

class Product
{
  protected $session;
  protected $obj;
  private $module;

  function __construct($one,$two) {
    helper(['html', 'url', 'form']);
    $this->obj = $this;
    $this->session = \Config\Services::session();
    $this->session->start();
    $this->module = $this->session->get('modulevalue');
  }

  function Check_operation($final,$operation)
  {
    if(isset($this->obj->module[$final][$operation]))
      return 1;
    else
      return 0;
  }

}

in basecontroller.php

Code:

protected $libcon;
public function initController(\CodeIgniter\HTTP\RequestInterface $request, \CodeIgniter\HTTP\ResponseInterface $response, \Psr\Log\LoggerInterface $logger)
    {
        $this->libcon= new Product($one,$two);

    }

in products.php controller

Code:

<?php namespace App\Controllers;

class Products extends BaseController
{
    public function recentPosts()
    {
        $data = [];
        echo view('templates/header', $data);
        echo view('products');  // here in above products view file i need to access libraries Check_operation , and this i have to used in multiple view files
        echo view('templates/footer');
    }

}

How i can i access libraries Check_operation in above products view file

view file of products.php

i taught of using

Code:

<?= view_cell('\App\Libraries\Product::Check_operation', ['4' , '7']) ?>

but it giving me ArgumentCountError 0


in ci3

we can use directly in view

like

Code:

<?php $this->libcon->Check_operation(4,7) ;?>

but ci4 - cant
