Livy Session Timeout when on EMR serverless application

I have been testing out using Livy endpoint from a EMR serverless application according to this documentation: https://docs.aws.amazon.com/emr/latest/EMR-Serverless-UserGuide/interactive-workloads-livy-endpoints.html. I sometimes got "{'msg': "Session '2' not found. It could have been cleaned up due to session 'idle timeout.'}" after not sending request for a while, I assume there is a parameter in the Livy config that controls the timeout, is there any way it can be modified?
