AWS Amplify Gen 2 - Add Existing S3: Where to find settings "AWS-account-ID" and "role-name?

I am following the docs here: [Use Amplify Storage with any S3 bucket](https://docs.amplify.aws/angular/build-a-backend/storage/use-with-custom-s3/

In the first step, it's asking to edit the S3 bucket policy with the following information: Replace with your AWS account ID and with the IAM role associated with your Amplify Auth setup.


Where can I find the "AWS-account-ID" and the "role-name"?

I am guessing that the "AWS-account-ID" is the ID found in the Amplify App Settings where it says App ARN:

I can find the Cognito User Pool associated with my Auth, but I am not sure where to find the "role-name". (There are about 200 roles in my account). The existing S3 that I want to re-use was created with Amplify Gen 1 v5.

The documentation should explain those steps in more details.
