Parameters in javascript form rules

0

Hello everyone,

I have a JavaScript form rule with parameters that lives in a script tag in an HTML form field. And I have the issue that I can't figure out what button combination I need to press or where to click to edit the parameters.
With business rules, it's in a context menu, but within the expression editor on the HTML field, I can't figure it out. And I could not find anything on the forum or documentation.

I'd appreciate any advice.
