OTBI report prompt to display only direct reports for Line managers

Summary:

We have created an OTBI report using the subject area - 'Workforce Learning - Learning Management Real time'. We have created a prompt which displays all the Employee names while running the report. Now, we want to limit the prompt to only display the direct reports names for the line managers when they run it.

Can you please suggest how we can modify the prompt to limit it to display only the direct reports?
