Unable to list courses using API

I’m wanting to use the Docebo API to return all Courses
using either endpoints:
- /courses/v1/courses
- /learn/v1/courses

Both of these return Http Response code 200 but with 0 items
Below response is from endpoint: /courses/v1/courses

{
    "data": {
        "items": [],
        "count": 0,
        "has_more_data": false,
        "cursor": null,
        "current_page": 1,
        "current_page_size": 100,
        "total_page_count": 0,
        "total_count": 0
    },
    "version": "1.0.0",
    "_links": []
}

I can successfully call endpoints:
- /learn/v1/courses/{{CourseId}}
- /learningplan/v1/learningplans
- /learn/v1/lp
- /learn/v1/lp/{{LearningPlanId}}

My current setup:
Authentication: Local service account (username & password) 
                         Power User using a Profile to manage permissions
User Assigned Resources:
- All courses and learning plans

Profile Permissions:
Courses - View
Learning Plans - View
Users - Create, Can active users, Edit, View

I’ve tried making the service account a Super Admin but it still does not return courses

Are there any other setup I need for courses to be listed via the API?

Edit: I can successfully list courses when using own account (via OAUTH) on Docebo API Explorer, but I need to use a local account for my app.
