Meet Chat Transcribe

Does this only work in the paid version of google meet? I was logged in to google, selected the transcribe butting, had captions going... but now just gettting the error '# 2020-04-27 null' when I paste. No Meet Transcripts folder in the drive. So. what went wrong? Did I use it wrong, or does it just not work?

DID NOT WORK!!!!!!!!!!!!!!!!!!!!! DO NOT ADD!!!!!!!!!!!!!!!!!!!!!!!!!

Not working. The button "Transcribe chat" doesn't appear on the bottom panel

USELESS!!!!!!!!!!

its giving constant issues, doesnt work and even after removing the extension it keeps opening a window for login.
