How to implement virtual participant in Google meet call?
And to get the transcription in real-time?

I am working on a chrome extension that I would like to offer to around 500 people for free using the Google People API.
Does anyone know the usage costs for the Google People API? I am trying to figure out if this free model approach is feasible.

Please help me fix the error so that I can record voice directly from google site!
I write the google app script web app to record audio.
I tested the web app, it works perfectly.
