How to hide/unhide system field "Component/s" using behaviour

[WindHub Support]

I've been searching through the questions but couldn't find a working way to hide the m field "Component/s"

I've been using this formula for custom fields:

def CountryField = getFieldByName("P-Country")
CountryField.setHidden(true);

what would be the equivalent way for "Component/s"?

My team imported many years ago from Test Track Pro, but I don't recall what magic we did to accomplish.

Today starting from XML or CSV, I would write a simple script capable of generating a JSON format that will allow you to add comments. If you are not a developer probably your company should contact an Atlassian Partner to assist you.
