UPDATE

Download html5-chat plugin from this link

Edit application\modules\Html5Chat\controllers\indexController.php
And insert that script

<?php

class Html5Chat_IndexController extends Core_Controller_Action_Standard
{
  public function indexAction()
  {
      $webmasterid = 'xxxxxx'; // change that
      $password = 'yyyyyy'; // change that

      
      $viewer = Engine_Api::_()->user()->getViewer();
      $userid = $viewer->getIdentity();
      $username = $viewer->getTitle();
      $fields = Engine_Api::_()->fields()->getFieldsValuesByAlias($viewer);
      $user = Engine_Api::_()->getItem('user', $userid);
      $avatar = $user->getPhotoUrl('thumb.profile');
      $profileLink = $viewer->getHref();
      $gender = 'male';
      $role = $user_level = Engine_Api::_()->user()->getViewer()->level_id;
      $roleLabel = Engine_Api::_()->getItem('authorization_level', $role)->getTitle();
      switch($fields['gender']) {
          case 1:
              $gender = 'male';
              break;
          case 2:
              $gender = 'female';
              break;
          case 3:
              $gender = 'couple';
              break;
      }
      switch($roleLabel) {
          case 'Superadmins':
              $role = 'admin';
              break;
          case 'Admins':

          default:

OLD (BAD) WAY

We will add the link chat into /groups/chat so your chat link will be
https://yoursite.com/groups/chat

edit /application/modules/Group/controllers/IndexController.php
And add this function

public function chatAction() {
    $webmasterid = xxxx;
    $password = 'yyyy';
    $viewer = Engine_Api::_()->user()->getViewer();
    $userid = $viewer->getIdentity();
    $fields = Engine_Api::_()->fields()->getFieldsValuesByAlias($viewer);
    $user = Engine_Api::_()->getItem('user', $userid);
    $avatar = $user->getPhotoUrl('thumb.profile');
    $profileLink = $viewer->getHref();
    $gender = 'male';
    $role = $user_level = Engine_Api::_()->user()->getViewer()->level_id;
    $roleLabel = Engine_Api::_()->getItem('authorization_level', $role)->getTitle();
    switch($fields['gender']) {
        case 1:
            $gender = 'male';
            break;
        case 2:
            $gender = 'female';
            break;
        case 3:
            $gender = 'couple';
            break;
    }
    switch($roleLabel) {
        case 'Superadmins':
            $role = 'admin';
            break;
        case 'Admins':
            $role = 'admin';
            break;
        case 'Moderators':
            $role = 'moderator';
            break;
        case 'Default Level':
            $role = 'guest';
            break;
        case 'Public':
            $role = 'guest';
            break;
        case 'Monthly Member':
            $role = 'user';
            break;
        case '6 Month Member':
            $role = 'user';
            break;
        case 'Yearly Member':
            $role = 'user';
            break;
        case '15 Day Free Membership Trial':
            $role = 'guest';
            break;
        default:
            $role = 'user';
            break;
    }

    $json = json_encode(array(
            'id'=>$userid,
            'username'=>$fields['first_name'],
            'password'=>$password,
            'gender'=>$gender,
            'role'=>$role,
            'image'=>'//'.$_SERVER['HTTP_HOST'].$avatar,
            'profile'=>'//'.$_SERVER['HTTP_HOST'].$profileLink
        )
    );
    $encoded = file_get_contents("https://jwt.html5-chat.com/protect/".base64_encode($json));
    $this->view->script = "https://html5-chat.com/script/$webmasterid/$encoded";
    $this->_helper->layout->disableLayout();
}

replace xxxx by your webmasterid and yyyy with your html5-chat password

You can get values profil type from table engine4_authorization_levels

create chat.tpl in application/modules/Group/views/scripts/index/

<!doctype html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
    <meta http-equiv="X-UA-Compatible" content="ie=edge">
    <title>Chat</title>
</head>
<body>
<script src="<?=$this->script?>"></script>
</body>
</html>

and you will get your own chat on /groups/chat
