Local recording interpretation channels

Hello!

I recently managed a hybrid meeting on Zoom that was interpreted and locally recorded. Throughout the session, I switched between language channels to check for technical errors and assess the interpreters' performance. I just exported the recording but there's only one video file which switches between the language channels as I did, with no pure English, Spanish, and Main Audio files.

As a record of the meeting, I need a pure Main Audio recording. I know that this is provided when recording on the cloud. How can I access this from a local recording?

Any help is welcome!
