Is there a way to see which AWS IAM User/Role Matillion is using?

Is there a way I can check what IAM user and role Matillion is using by default? This feels like a dumb question, but I can't figure out where to find this.

Hi there @ZachB​ and thanks for being here!

We have some documentation here about IAM roles & permissions (AWS) that might be of help? Take a look and let me know how you get on.

Many thanks,

Claire
