Interface does not contain the Workspace menu

If see docs on this page we see Workspace menu in the Unreal Editor, but in my Editor does not contain the Workspace menu and can not access to Unreal Frontend from editor.
And if i try launch manually Unreal Frontend he looks different than in the documentation.
What should I do to have the Editor and Unreal Frontend looked like in the documentation?

Unreal Editor and Unreal Frontend have changed somewhat since we originally created that documentation. We plan to update it in the near future. The menu in Unreal Editor is called Window now and the tools you want are Device Manager and Session Frontend. If you have specific questions about using either of those, please post them here or on the forums and we will try to help you out.

Sorry for the confusion caused by those older pages.
