Accessing command options in ansible tasks

I’m developing workflows that use ansible tasks to provision a launched VM. In the Create Instance dialog, I get the the Automation stage, and when I select my workflow, a field pops up for each Ansible task that says “Command Options”

I can’t find anything in the docs that explains what format to use here enter data, or how to access that data in ansible when I do. Can anyone point me in the right direction?
