Streaming radio stations through Chromecast

I see that Chromecast is supported in HA. Can someone explain how I can cast a radio station (example : livestream-redirect/SKYRADIOAAC.aac ) to one or more of my Chromecast devices and at a specific day and time?
I am not very technical and not good at programming . Step-by-step instructions work best for me. THANKS !!!
