Device Auth Flow: How to add a device name?


I’m using a device auth flow in my app.
The question is, in this link, the example output and its comment seems to show that the app can provide a “device_name” as a query param to set a name for the device that is being authenticated.

Below is the example code from that page.
“id”: “dcr_dFJiaAxbEroQ5xxx”,
“device_name”: “my-device” // the value of ‘device’ provided in the /authorize call when creating the token

However in the Auth0 Dashboard, we don’t see the device name we passed in but instead “okhttp” is shown and seems like auth0 might have gotten that from the useragent.
Could you please advice what the correct way of setting a device name would be?
Thank you.
