Getting Started with Roon 2.0 ARC

I have downloaded Roon 2.0. And then set up the ARC function on my Android phone. There is a message which says your CX is Antipodes CX is not set up for remote access. I am looking to use ARC when driving (currently use Tidal). Can anybody point me in the direction of what I need to do to set up the CX to allow it to be accessed remotely? Thanks in advance
