I'm getting an "Invalid_scope" error, even though I used an access token generated with the correct scope.

Here’s what I did in Postman:
  1. Generated the code to create an access token using the following URL:

    https://accounts.zoho.eu/oauth/v2/auth?scope=ZohoCampaigns.contact.UPDATE&client_id=<client_id>&response_type=code&access_type=offline&redirect_uri=https://1882-2-26-193-161.ngrok-free.app

    (Used ZohoCampaigns.contact.UPDATE as the scope).

  2. Successfully generated the access token.

  3. Sent a request to subscribe to the campaign.



However, I received an "INVALID_SCOPE" error.

Does anyone have any ideas?
