@uchitsa thanks for the contribution! The code looks good, but some CI workflows don't pass. Please, check.

@yegor256 let's try the workflows again please

Run aws-actions/configure-aws-credentials@v4
Error: Credentials could not be loaded, please check your action inputs: Could not load credentials from any providers
