oci sdk invoke

Summary:

I have an existing python process that calls SDK objects, for example list_refresh_activities. I want to put this in to a function and invoke it as a rest endpoint but cannot find any useful examples.

How to I invoke list_refresh_activities and what does the payload look like for the fn ?
