Good points, the oauth integration uses the users permissions that you authenticate with. So, when you hit the oauth it will prompt you to follow the login workflow. You will need to make sure that your user that you logged in with is a user in that profile that you showed in the screenshot that has all the permissions. Adding the integrations is specifically for service token/jwt integrations. Because they behave as their own user, you need to give them access to a profile for permissions. But, because you used oauth that uses your own adobe permissions for the user you authenticated through. If all that is in order, than it may not be a product profile/permission issue.
