How to add a section or tab in Joomla 3x module admin panel?

Question

Joomla

I have a custom module in Joomla. Everything works, but you need to make three sections for three elements in the admin panel. I don’t understand how to write in the code so that each group of parameters has its own name, as in the picture, what is written in red.
helper.php

<?php

// No direct access
defined( '_JEXEC' ) or die;

/**
 * Class Module Helper
 * @author Татьяна Егорова
 */
class modConditionHelper
{

  /**
   * getData method
   * @param $params
   * @return array
   */
  static function getData( $params )
  {
    $db = JFactory::getDbo();
    return array();
  }

}

mod_condition.php

<?php

// No direct access
defined( '_JEXEC' ) or die;

require_once( dirname( __FILE__ ) . '/helper.php' );
$data = modConditionHelper::getData( $params );
$moduleclass_sfx = htmlspecialchars( $params->get( 'moduleclass_sfx' ) );
require( JModuleHelper::getLayoutPath( 'mod_condition', $params->get( 'layout', 'default') ) );
