OAUTH2 client credentials token request error 'Bad request'

Hello everyone,

I'm facing issues with the oauth2 token request in Power Query. See the query below:

let AccessToken = Json.Document(Web.Contents("xxx", [ Headers=[Accept="application/json", #"Content-Type"="application/x-www-form-urlencoded"], Content=Text.ToBinary( "grant_type=client_credentials& client_id=xxx& client_secret=xxx& scope=xxx" ) ])) in AccessToken

I'm facing the error below:

In Postman, I succeeded to get a response with token.

Could anyone provide any help?
