Unable to Create Service Connection to FA Services

Summary

Create Service Connection raises 'The user is not authorized'

Content

Running OIC-Classic version 19.3.1.190518.1400-28490

Creating a Service Connection to the FA Instance registered in Settings, raises:

Error loading FA Services

Error: The user is not authorized

The user account that is logged into OIC has the following roles in Fusion Applications:

1) IT Security Manager

2) Integration Specialist

3) Role to use HCM REST Services

The VB documentation does not detail what roles are required in FA to use this feature.

Can anyone assist?

Many thanks!
