Unable to edit Info.plist in Xcode 16.2

I am trying to add complication feature to my watchOS app. I need to add some keys to the Info.plist.

Project Navigator - no Info.plist file (as expected)

Target watchOS > Build Settings > Info.plist values.

I am unable to add a value. Hovering over a row does NOT show small '+' or '-' icons.

How do I edit the Info.plist?
