Contact_center.voicemail_transcript_completed Does not Provide a Useable Transcript URL

API Endpoint(s) and/or Zoom API Event(s)
Contact Center Voicemail Transcript Completed

Description
I am developing a custom integration between Zoom Contact Center and my company’s internal Deskpro helpdesk. I am using a few webhooks to trigger actions when engagements are started. The webhook itself works fine and returns a download URL like this: https://us01cci.zoom.us/v1/account/inbox/voicemail/transcript/download?inboxId={inboxId}&contentId={contentId}

However, any attempts to query this URL are met with a 401 error. How can I programmatically query Zoom for both the audio recording and the written transcript of a CC voicemail?

Error?

{
    "status": false,
    "errorCode": "401"
}
