SQL Workbench: You don't have permission to view the scheduled query history

Hello community,

I am baffled by the following message from the Query Editor

You don't have permission to view the scheduled query history. To view, add sts:AssumeRole for IAM role to your IAM role and add your IAM user ARN to the role's trust policy.

I followed this this documentation steps to allow access, which did change the error message, however it looks like it's not enough. I am a bit perplexed as to what to do next. The message itself a bit cryptic.

I would be glad for any piece of advice.

Regards, Peter.
