Are you very sure you’re downloading a VTT file??
It looks like Zoom’s recordings are in m4a (Audio format), try using a module like the OpenAI (ChatGPT, Sora, DALL-E, Whisper) “Generate a transcription” module —
Transcribes an audio to text.
For more information about the “Generate a transcription” module and the OpenAI (ChatGPT, Sora, DALL-E, Whisper) app, see the corresponding Integrations page and the Help Centre documentation.
Hope this helps! If you are still having trouble, please provide more details.
