Fetch Audit logs at organization level using Fliplet provided REST API

Hi, I am here with a problem statement, I just want to get audit logs at organization level from Fliplet using Fliplet REST APIs.
I facing difficulties while generating audit logs using API. I am getting below error in postman tool :
“error”: “admin access only”,
“message”: “You must be an admin to access this route.”
I have admin level of permission and in Fliplet UI, I am able to view audit logs.

Please assist me. Thanks Ashish
