how to add a new chromebook to an existing reviewer account

ChrisSr

I have a tv account with a few Windows laptops listed and accessible. I now have a new chromebook which I want to access remotely using this tv account from one of these machines. I have installed the Chrome version of tv and have logged in on the Chromebook. However the Chromebook doesn't have a machine name in the same way as the Windows machines and I am at a loss to know how to include it in my list of tv machines. Any pointers gratefully received. THanks.
