AWS CloudFormation Template - How to configure Lambda with a SQS queue to pick the item from queue

I am pretty new in AWS CloudFormaton template creation. Could not able to find the way to create a Lambda function which will connect with the SQS queue.

Any example or resource would help me to learn and implement.

You need:
