Issue Summary

The totalSize field is missing from REST API responses, making it hard to implement pagination for big instances.

Endpoint used for test: https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-group/#api-wiki-rest-api-group-get. 

In case this field is deprecated/removed, please update the documentation with the current information.

Steps to Reproduce

1. Send a request to the endpoint GET groups, and check the response body.
2. Please note that this happens to multiple or even all endpoints on Confluence Cloud. Other endpoint example:[ https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-group/#api-wiki-rest-api-group-groupid-membersbygroupid-get|https://developer.atlassian.com/cloud/confluence/rest/v1/api-group-group/#api-wiki-rest-api-group-groupid-membersbygroupid-get]

Expected Results

As shown in the documentation, the response should have a totalSize field:

{
  "results": [
    {
      "type": "group",
      "name": "<string>",
      "id": "<string>",
      "_links": {}
    }
  ],
  "start": 2154,
  "limit": 2154,
  "size": 2154,
  "totalSize": 150,
  "_links": {}
}

Actual Results

Response comes with no totalSize field and value:

    ],
    "start": 0,
    "limit": 200,
    "size": 13, 
    "_links": {
        "base": "https://{SITE}.atlassian.net/wiki",
        "context": "/wiki",
        "self": "https://{SITE}.atlassian.net/wiki/rest/api/group"
    }
}

Workaround

Currently, there is no known workaround for this behavior. A workaround will be added here when available.
