I followed the Microsoft doc to get the billing profile of a customer.
With the auth [tutorial] I deployed following Powershell Code
`$credential = Get-Credential
Connect-PartnerCenter -Credential $credential -ServicePrincipal -TenantId '<TenantId>'`
I than copied the access token and produced a Postman Get request but still got an 401 unauthorized request
It could be from the security update of Microsoft , but the Auth documentation is from january so i think These are the steps to get access to the partner central
Or I don't have the right permissions as a user to get the billing profile.
I know it's one step that I oversee or that it's one thing that I did wrong but I can't see it
I am aware that there are some questions online about this issue. But Can't seem to find a solution there.
[Edit ] Tried to access the bearer token by firstly accessing the refresh token via this powershell code
$credential = Get-Credential$token = New-PartnerAccessToken -Consent -Credential $credential -Resource https://api.partnercenter.microsoft.com -ServicePrincipal
But keep getting following error : 
Even when i added the URL in the redirect URL setting:
Is there someone who already tried this or sees what i am missing here ?
