Sonos not showing up in Google Home (via HA of course)

Hey all - very new to HA so apologies if this is so trivial it has never been asked. HA is working with the Sonos integration. All good. HA is added to Google Home. All good again. All my Hue lights, added via HA show up in Google just fine. But I’m not getting either of my Sonos Amps coming through to Google at all. I’m sure it’s something I’ve missed. I did search the forum but all the relevant threads are about more nuanced issues with the Sonos integration. I’m just assuming that I can use HA as my aggregator for all my smart devices and then Google ONLY needs to have HA added and I’m good to go. But maybe not?

Not all entities are exposed to GH by default.
I believe the settings are under cloud settings, manage entities or something like it if I remember correctly.

See if it’s exposed there first, then update the entities in GH by asking to sync devices.

Brilliant! Yep - that was it! And it answers my next question about what Hue lights/groups/etc I expose to GA! Magic! Thanks mate.
