VS Code Typescript: expand type tooltips

Question

I've been trying for way too long to get the VSC tooltip to show me a function's parameters' properties:

Hovering over an Interface gave me nothing:

Example with an inferred type:

Or this beauty VS Code gives you while typing:

Did just discover the "Add Missing Properties" which looks amazingly helpful:

Thank you for your help!

Recursive introspection is kind of a sore spot in TS. However, you can use cmd / ctrl + click on a type name to go to the place where it's defined (or view a list of references if there are multiple).
