How to Properly Comment Functions in Monkey C Using VS Code

Is there a way in VS Code to add a comment or documentation to a function so that it appears as a tooltip or suggestion when using the function elsewhere in the code?

I've tried some common documentation formats, but haven’t been able to get it working.

For example, I tried this:

/*!
 * Constructor
 * @param item - the menu item to be associated with this command
 */

But the comment doesn't show up when I type the function name elsewhere. Is there a specific format or extension required to enable this?
