Copilot Employee Self-Service Agent

I see that Microsoft has put a lot of efforts to marketing the Copilot Employee Self-Service Agent but it seems it is not available for every tenant. 

I have already checked on several small and mid ones (5-2k users) and cannot install it. 
As I understand from what I already red and saw, this is a template that should be available to you when you start building agents. Unfortunately when I enter Copilot Studio and enter in the search ESS (abbrevation from Employee Self-Service) I got only those two marked red filtered. 
When I installed IT Helpdesk, I do not see topics related to HRSD in ServiceNow which I need. 
I found the Employee-Self-Service-Agent-Developer-Kit that contains same examples of the ServiceNow HRSD topics, but when I copy the code of those to my agent I got some references to topics that I do not have. 

Anyone has struggled with the same? Or maybe you have access to the ESS agent and can share the topics with me?
