Cubase AI 11 tempo track

Hello everybody. Cubase AI 11 let me access to track tempo editor but I can´t create or add a tempo track in teh main window. The option “add tracks” offers all kind of tracks but teimpo. Why is that?
How could I create a tempo track? Even though I can access to its editor, the tempo track doesn´t appear in the main window. Could you help me to get htat?
Thank you.

Sorry, but the Tempo Track in the Project window is only available in Cubase Artist or higher. In Cubase Elements and Cubase AI, tempo can only be edited from this separate window.

Ok, thank you. So Steinberg sholdn´t write in the Cubase AI 11 manual that we can create a tempo track.
Greetings.
