How do I begin EvalGen process?

[lbaierreinio]

Can you clarify how you can actually use EvalGen? I don't see anything in the UI for it after running chainforge serve and the instructions suggest There is an interactive script to play with the functionality in test.ts. You can run it by running ts-node test.ts in the grading directory of the project. The terminal is a bit laggy sometimes., but I don't see a grading directory in the file structure

You have to hook a MultiEval node to the output of a Prompt Node (or anything really with downstream outputs). Then you will see the button.
