Chromecast alarm

Hi all. I’m using hassio and I would like to somehow be able to set an alarm that casts Spotify at a fixed time every day on a Chromecast. I know I can do this with the Google Home speaker but since I have some nice speakers on the chromecast TV I would like to be able so use those instead of one of my Google Homes. I looked around a bit for an answer but haven’t had any luck. Any pointers are appreciated.

Doesn’t need to be Spotify at the end of the day. It can be Youtube or whatever works!
