Trigger server action when database field is empty

Hello,

I’m a little stuck and the research on the forums I’ve done haven’t helped. I have two database fields, one is a toggle (1/0) and the other contains a date. I have a server-side flow that updates the toggle field fine, and I want to set up an update action on the field that contains the date only if said field is empty. If the field is not null, then I don’t want it changed.
