Select which user will be used to execute this post function. By default this parameter is set to the current user. You can also use field codes to run the function as a dynamic user (e.g. current assignee).
Make sure that the user running the post function has all the relevant permissions to perform the actions defined in the configuration (e.g. "Update Issues")!
If you want to keep track the actions being performed automatically, we suggest to create a dedicated JWT account, granted all relevant permissions, and use it in the Run as parameter to identify which changes have been made with JWT.
