How can I get Closed Caption with Speaker?

Hello,

In order to apply Japanese transcription and get it after a meeting, I set Audio transcription with Japanese in account setting.

I can check Japanese transcription with Speaker name in Zoom meeting. I downloaded Closed Caption after this meeting, but this does not include speaker name like normal VTT(Audio transcript).

If I get Japanese Closed Caption(transcript) with speaker, I would like to know how to get.
