Basically what the question says!

I’m thinking about moving from Spotify (useless app that bugs out all the time - questionable business practises etc...) but I’m struggling with one bit of functionality.

With Spotify if I ask my Google Home to play Deezer it will, but I can’t then control it from the Deezer web player? For example if I want to skip a track or play another playlist?

I thought maybe casting it directly from the Web player would solve this but when I click the cast button it doesn’t give me any option to cast to my Google home?!
