Still no cast to Chromecast devices from Apple Music on IOS?

Weird that I can cast from Apple music to all my Chromecast devices from Apple Music app installed on an Android device, but not from IOS devices (iPhone 15 / iPad mini 6).

Am I missing something?

Other services work (tried YT music, Spotify, Yousee music (Danish provider), it just makes me chose them over Apple Music, as I don't want to buy new speakers.

Bummer since I just switched from the dark side ;-)

My Harman Kardon Citation One do support Airplay but it's mono only, and I have 2 setup as a stereopair in Google Home.
