How to cancel creating an Agent in Teams?

Oy!  I am pretty new to this.  I went to Teams and saw the Copilot button on the Navigation Bar on the left. I clicked it and saw the normal "home page" or Chat page or whatever it is called.  I clicked the Create button and bounced right into the initial New Agent screen.  I'm not ready for that, but now I cannot get out of it.

I still the Teams Navigation Bar where I can click on the other apps in Teams, but when I click on the Copilot button again, I am back into the New Agent screen.  

I also tried clicking the Teams Back button "<" and that does what it should but back to the Copilot screen, I now only see the New Agent screen.

HOW do I get out of this and back to the normal Chat screen?  I see no cancel button or any such thing.  HelP!
