Sonos Voice Control works out and about (in a basic way)

I’m currently on holiday, renting a cottage on the south coast of the UK. Took one of my Roam’s plus my Move with me to use with Bluetooth and I’m super impressed to find that Sonos Voice Control works on the speakers in a basic way on both the Roam and Move speaker. It will play/pause/go forward or back a song etc. I did notice when I got here that both white mic lights were on which I didn’t expect, but obviously they are on because it will work with basic functions (speaker only functions, rather than app functions). Do any of the other voice assistants works with a portable Sonos speaker out and about? I used to use Google Assistant but hadn’t at that point, taken any of my portable speakers out and about, so don’t know if it would have worked or not. I’m guessing not.
