Unfortunately, since Google apparently is hell bent on preventing desktop apps from (officially) being able to Cast (probably to keep Chrome the only browser with the capability), the Spotify desktop app doesn't have the ability to cast. Spotify should have held out for desktop casting ability; all they have done is fragment their great Connect.

This feature is a long time coming. If you’re a regular Chromecast user — as I am — you’ll probably relate to the frustration of not being able to start a Chromecast stream from your desktop. In fact, this was one of the benefits of running the Spotify mobile app in Chrome OS desktop, and running the iOS version on an Apple Silicon Mac would have allowed this functionality as well.

Thankfully, it looks like we’ll all forever be able to start those Cast streams straight from the desktop — no workarounds required.
