How to collect OS level logs on from Mobile devices attempting access to Application behind Application Load Balancer

Need help identifying how to collect OS level data on mobile applications attempting to log into web server hosted on an EC2 windows machine. We are using Cognito as well as an ALB to route traffic. Would like to collect OS level information (Iphone SE, Samsung Galaxy etc.)

Is there a way to configure this natively in AWS via Cloudwatch or Cloudtrail? Was not able to see from the documentation. Thank you
