I've previously selected the "Do not show hints for the current method" context action for a method to hide its parameter names, but now I'd like to undo that selection.
How do I make the hints again visible for that method?
The context actions don't show an option to show the hints for the current method after they have been hidden. I can't find in settings a list of methods for which hints have been disabled. I can't find a mention of that method in the configuration files inside the .idea directory.
The list of methods whose parameter names have been hidden can be found in the settings at Editor > Inlay Hints > Parameter names > JavaScript. On this page there is a link to the Exclude list. (Note that it's on the "JavaScript" node of the tree, and not on any of the leaf nodes of the tree.)
