Create homekit automation to play radio on appleTV

I use apple TV to play local radio, and i just to create an simple automation to do it in the morning.

I created a new automation on Homekit on the ipad, so far so good, but then i can not setup the name of the radio, it ask me pay for apple Music??

This is strange because it is just free tuneIn radio, and it work well when using AppleTv Music directly

This kind of automation should be possible, i just want to run radio at 8am like i was used to do with a cheap equivalent google speaker.

May be a missed something?
