Query Athena using a Cross-Account IAM Role

This script demonstrates how to query an AWS Athena table from a different AWS account by assuming an IAM Role. It uses the AWS SDK for JavaScript v3.

Description

The script performs the following actions:

1. Assumes a Cross-Account Role: It uses the AWS Security Token Service (STS) to obtain temporary security credentials by assuming an IAM role in a target AWS account. This is a secure way to grant temporary access to your AWS resources to users from other AWS accounts.
2. Executes an Athena Query: Using the temporary credentials, it connects to Amazon Athena and executes a SQL query against a specified database and table.
