Unable to connect to EC2 instance in aws labs

I’m trying to connect EC2 instance using ssh in kodekloud aws lab session but i do not have .pem (Private Key) for particular instance. Where exactly .pem file located in lab sessions?
EC2 instances are pre-configured with key pair by kode Kloud, I would like to know how to retrieve .pem file so that I can connect via ssh

Please post the link to a lab you are having issue with

LAB - Moving a volume from one EC2 instance to the next - KodeKloud

The PEM file should be found in /home directory
