Can I produce a Meeting Summary from a recorded session when AI Companion was not turned on?

[pieemme]

I forgot to turn on AI Companion, thinking it would be automatically on (I had the impression this was the case with earlier meetings).  Is there the possibility to have AI Companion to produce a Meeting Summary afterwards, based on the recorded session?  I tried in vain to use an external LLM to produce a Meeting Summary but it needed a lot of information only available to the Zoom platform itself.
