Device Authorization: "unsupported grant type" requesting access token

__
Meeting SDK Type and Version
zoom-sdk-windows-5.13.10.13355
My app is a Meeting SDK App

STEPS
First get a device_code like this:

curl -X POST https://zoom.us/oauth/devicecode
-d ‘client_id=’
-d ‘client_secret=’

Visit the verification URI to add the app.

Now use the device code to request an access token.
Here is the attempted POST:

*curl -X POST https://zoom.us/oauth/token *
*-H ‘Content-Type: application/x-www-form-urlencoded’ *
*-H ‘Host: zoom.us’ *
*-H ‘Authorization: Basic ’ *
-d ‘device_code=&grant_type=urn:ietf:params:oauth:grant-type:device_code’

Here is the error response:
{

  • “reason”: “unsupported grant type”,*
  • “error”: “unsupported_grant_type”*
    }

Troubleshooting Routes
I am able to use my server-to-server OAuth flow to create access tokens, but I need to figure out device authorization for this app.
App is Live, but not published (no intention to publish)

How To Reproduce
See steps above.
