API call

Hi!
I am a developer building a standalone automation service using the Trados Public API. I need to set up a Service User for OAuth2 Client Credentials authentication, but I cannot locate the 'Service Users' management area in my current dashboard.

Can you please:
Point me to the exact location of Service User management for my tenant?
Confirm if my current subscription tier supports Public API access and the creation of Service Users?
Verify if OCR (Optical Character Recognition) is enabled for my account's file-type configurations so I can analyze JPG/PNG files?

Thank you in advance.
