I am trying to use the merchandised_products endpoint from Marketing API. According to the documentation, this requires the `https://api.ebay.com/oauth/api_scope/buy.marketing` scope. However, this scope is not available for my production keyset (Client Credential Grant Type).
I applied for additional API access but was informed that the Marketing API does not require approvals and can be used immediately.
Could you please advise how I can add the `buy.marketing` scope to my production keyset?
