Trying to access the token for further use. I get response "unsupported_grant_type"

Please try the following cURL to get token

curl --location --request POST 'https://sts.nordpoolgroup.com/connect/token'

\--header

'Authorization: Basic Y2xpZW50X21hcmtldGRhdGFfYXBpOmNsaWVudF9tYXJrZXRkYXRhX2FwaQ==' \--header 'Content-Type: application/x-www-form-urlencoded'

--data-urlencode 'grant_type=password'

--data-urlencode 'scope=marketdata_api'

--data-urlencode 'username=YYYYYYYYY'

--data-urlencode 'password=XXXXXXXX'

inserting your username instead of YYYYYYYYY and password instead of XXXXXXXX.
