Assistance Needed for Salesforce Webhook People Search Issue

Hi there, Can someone assist with People Search? We want to run it using a Webhook within a Salesforce-managed package. When the webhook is triggered, the record starts running People Search, but it does not return new records. Instead, it displays 'People Search Updated' without adding new records to the separate People Search table. It only works when we manually go to the People Search source and click 'Update Table.' "Auto-update" and "Enable Automatic People Search Updates" options are enabled
