Is your feature request related to a problem? Please describe. When running an onFlow from the DevUI it's really easy to forget to provide an auth object, and then I have to go in an type one in.

Describe the solution you'd like Would it be feasible to provide some sort of dummy auth JSON out of the box, to make this easier?

Ideally it would "just work" from the DevUi to hit run.

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
