Accessing Teams Meeting Transcripts via Microsoft Graph API

Question

There is a requirement to access the MS Teams meeting transcript programmatically while a call is being recorded for offline processing.

The question is whether it is possible to access the meeting transcript from memory cache during an ongoing meeting, or if access is only available after the meeting concludes and the transcript file is created.

While it is possible to download the transcript through Graph API after the meeting, clarification is needed regarding access during an active session. Any insights from those who have encountered this scenario would be appreciated.
