Universal Print (UP) Printer Registration Invalid Invalid Token, The Audient Invalid

According to the document https://docs.microsoft.com/en-us/universal-print/hardware/universal-print-oem-printer-registration , I obtained the Access Token in step https://docs.microsoft.com/en-us/universal-print/hardware/universal-print-oem-printer-registration#121322-retrieving-the-user-token Retrieving the user token.
This token can be used in the required authorization header (described in section 1.2.1.1.2) when sending a request to register a printer with Universal Print.
But when I send the request to api https://register.print.microsoft.com/api/v1.0/register
, an error code returned as 401 Unauthorized with description Bearer error = "invalid_token", error_description = "The audience is invalid"
Let me know what to do?
