How to assign an unattended runtime

I have an unattended runtime license that I want to assign to a machine. I watched a video tutorial in which the presenter opened the Edit Machine page and on that page there was a field in which he assigned the license, When I go to that page, however, I have no license fields, just machine name and machine key. Is this now done somewhere else? Any help would be appreciated.


Can you attach screenshot?

Here is the screenshot what I see when the Edit machine window is opened.

I don’t have those license fields:
