Filter Pendo API by product area and segment

Hi Pendo users, I built this functioning API script that extracts page related details by product area. Works great, but only give numbers for the "Everyone" segment. Is there a way to include a segment filter? I've tried to add the filter in multiple places and it does not work. Any help would be appreciated.

// Script Name: Monthly PageViews by Month by Product Area
// Description: Use this script to get PageViews, UniqueAccounts, UniqueVisitors from Pendo filter by Product Area. This is the same data fround in Product > Product Areas and filters by "D1P Risk Manager"
