I need to retrieve learning records through the REST API

I have a requirement to retrieve all Learning Cloud data using REST APIs. I have already tried using the endpoints provided in the official REST API documentation, but they return no data.

Could anyone help clarify:

• Which specific endpoints are recommended for retrieving learning records ?
• Are there any prerequisites (like security roles or profile options) that must be configured to access this data via API?

Any guidance or sample queries would be greatly appreciated.
