I have created an Omniscript who's components rely heavily on the current user's id. I am using the environment variable userId. An example of this is use is that I pass userId to a Dataraptor that returns the Contact information for that specific user Id.
I am able to test the different users by signing in as different users and opening up a page where the Omniscript is embedded. However, I would like to test different users in the Preview tab. Is there a way for me to override userId purely when I test the Omniscript?
