How about you assume less? I spent 40+ minutes looking for this here, here, here and here and I’m already fairly familiar having done work on two other ActivityPub based projects.
In addition public-addressing (or the lack of use thereof) in no way claims to achieve what you’ve stated - which is probably why it’s not the answer to my query.
I wonder if they’ll replicate the feature where a strange voice whispers your name (amongst other odd sounds) if you’re playing in the early hours.
Scared the crap out of me when that happened.
Edit. Evidence https://www.ttlg.com/forums/showthread.php?t=6529 to show I’m not mad.
