Windchill REST services Workflow domain

We recently updated our Windchill 11.1 system with CPS08. With this CPS, according to the documentation REST services are updated to version 1.5, and that I confirmed with command "windchill version".

In Windchill REST Services User's Guide for 1.5 it is stated that the new domain, workflow domain is introduced.

However, invoking the REST Api call "https://xxxx.yyy/Windchill/servlet/odata" doesn't list that domain:

[
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v2/ChangeMgmt",
"name": "PTC Change Management Domain",
"description": "PTC Change Management Domain",
"id": "ChangeMgmt"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v3/DataAdmin",
"name": "PTC Data Administration Domain",
"description": "PTC Data Administration domain",
"id": "DataAdmin"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v3/DocMgmt",
"name": "PTC Document Management Domain",
"description": "PTC Document Management Domain",
"id": "DocMgmt"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v1/DynamicDocMgmt",
"name": "PTC Dynamic Document Management Domain",
"description": "PTC Dynamic Document Management Domain",
"id": "DynamicDocMgmt"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v1/IE",
"name": "PTC IE Domain",
"description": "PTC Info*Engine System Domain",
"id": "IE"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v1/NavCriteria",
"name": "PTC Navigation Criteria",
"description": "PTC NavigationCriteria",
"id": "NavCriteria"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v2/PTC",
"name": "PTC Common Domain",
"description": "PTC Common Domain",
"id": "PTC"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v3/PrincipalMgmt",
"name": "PTC Principal Management Domain",
"description": "PTC Principal Management Domain",
"id": "PrincipalMgmt"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v3/ProdMgmt",
"name": "PTC Product Management Domain",
"description": "PTC Product Management Domain",
"id": "ProdMgmt"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v2/SavedSearch",
"name": "PTC Saved Search Domain",
"description": "PTC Saved Search Domain",
"id": "SavedSearch"
},
{
"path": "https://xxxx.yyy/Windchill/servlet/odata/v1/Visualization",
"name": "PTC Visualization Domain",
"description": "PTC Visualization Domain",
"id": "Visualization"
}
]

and it is also not visible in folder structure

Is there something wrong with our update, or Workflow Domain is not available for Windchill 11.1?

Thank you
