Unable to retrieve mpn profile

Question

We are trying to retrieve the profile using mpnId using Verify a partner MPN ID

https://api.partnercenter.microsoft.com/v1/profiles/mpn?mpnId=12345

But we are getting the following error :

{
"code": 400,
"description": "Access Denied.",
"data": [],
"source": "PartnerFD"
}

Enter the token issued from https://login.microsoftonline.com/{tenantId}/oauth2/token and the REST header value normally.

The result of the address below is displayed normally, and permission error occurs only when mpnid is added as a parameter.

Is there a part where you need to set the permission?
