How to retrieve employee name and entries with "Not Submitted" status using Concur Expense Entries A

[GIRITTH]

I'm using the Concur Expense Entries API (v3.0) – specifically this endpoint:
https://www.concursolutions.com/api/v3.0/expense/entries

I want to retrieve:

1. The employee name associated with each expense entry.

2. Expense entries that are not submitted (i.e., other than "Submitted" status).

So far, the documentation mostly shows examples with "Submitted" status. Is there a way to filter for unsubmitted entries, and also get the employee's name in the same response? Or do I need to call another endpoint for employee details?

Any pointers or examples would be appreciated!
