Easier way to find index id for setting up IAM Policy for AWS Q Business Connector

Hi.

I have been following the AWS documentation https://docs.aws.amazon.com/amazonq/latest/qbusiness-ug/s3-iam-role.html which shows example JSON file for IAM Policy. Is there an easier way to find index id for data source other than checking the JSON file from auto-generated IAM Policy JSON? I can't find index id from the console interface.
