                        </label>
                        <img src="\wordpress\wp-content\plugins\plugins-controller\spinner.svg" class="wsd-loading" alt="loading">
                    </div>
                </td>
                <td class="moderate">
                    <select class="wsd-payment-popup-select wsd-hidden" onchange="location = this.value;">
                        <option selected="" disabled="" hidden="">?????</option>
                        <option value="/wordpress/wp-admin/admin.php?page=wc-settings&tab=checkout&section=myfatoorah_direct">
                            ????? ???????

All things as css code is work But i DONTknow what I should ADD in my action function myajaxfunction_check at my plugin that to update payment state and active/ deactive should i use api to do that ? i add this code but not working well

dd_action('admin_enqueue_scripts', 'load_payment_style');
function load_payment_style()
{
  wp_enqueue_style('plugins_controller_style', plugins_url('style.css', __FILE__));
  wp_enqueue_script('plugins_controller', plugins_url('plugins_controller.js', __FILE__));
  wp_localize_script(
    'plugins_controller',
    'plugins_controller',
    array(
      'ajax_url' => admin_url('admin-ajax.php'),
      'ajax_nonce' => wp_create_nonce('plugins_controller')
    )
  );
}

function myajaxfunction()
{
  add_action('wp_ajax_nopriv_ccbs_ajax_function', 'myajaxfunction_check');
  add_action('wp_ajax_ccbs_ajax_function', 'myajaxfunction_check');
}
add_action('admin_init', 'myajaxfunction');

function myajaxfunction_check()
{     global $state;
      
     
    if( !empty($_POST['nonce']) && wp_verify_nonce( $_POST['nonce'], 'plugins_controller' )
         ) {   
               $response['code'] = " sucsess " . $_POST['nonce'] .$state."active" ;
          
        } else {
             $response['response'] = "You didn't send the param";
         
         }

         header( "Content-Type: application/json" );
         echo json_encode($response);
      
         // Don't forget to always exit in the ajax function.
         exit();
     
}

Are there any function i can use to active payment and deactive the same in woocommerce page ? thank you
