HomePod Minis — Groups and Follow-me Music capabilities???

I have several HomePod Mini’s scattered throughout my house.

Some are paired in a room, while others are singles.

Two questions:

1) As I understand it it’s possible for me to group some or all of them into a group where when I play music or the radio on an entire group, it will play on every speaker in that group. Correct? I’ve not yet figured out how to do that.

2) Does the HomePod Mini have the capability for “follow-Me” music? Obviously I could play the music on every speaker in the house simultaneously — but that seems a little excessive. When I am moving throughout the house a lot, like doing chores, it would be great if I could go into Home and set a device to follow — like my Apple Watch which I always wear — and the music would follow me to the speaker(s) nearest me as I move, automatically and uninterrupted. Is this possible?

Thanks in advance!
