How do I edit the Work Relationship Info fields from Termination's action in Redwood UI?

Hi everyone, I have a question.

I'm using Redwood UI, and in the Terminate Employment action, in the "Work Relationship Info" section, I need to hide the "Recommendation Authorized By" field and add the "Recommended for Rehire" and "Person Number" fields. However, when I go to Visual Builder Studio, these fields aren't there. How can I hide and unhide these fields?

Thanks in advance,
Jole
