Syntax highlighting in Vscode for type hints

Question

I am using the Dark++ theme but personalising a lot of colours.
Everything works fine but one small thing: only the basic types are properly highlighted.
For example this

"editor.tokenColorCustomizations": {
      "comments": "#707070",
      "keywords": "#adc5ee",
      "types": "#bbbbbb",
      "strings": "#bdceb7"
}

gives me the following picture:

I would like the type hints in the function declaration to be grey+italic, as it happens correctly for the type "str". I understand it is not straightforward for npt.NDArray as that comes from the typing module, but why is this not working even for "list" and "dict"?
And do you know of a workaround I could use?
There are not special tokens for these types as far as I know, so no way to access them other than just customising the general token "types".
I tried using regex expressions with the "Highlight" extension but that is not optimal, because I also want to keep the functionality that if I comment out part of that text, it should be greyed-out (using "Highlight" it doesn’t).

To close this topic and for future reference, this is how I solved my issue: I ended up using semantic highlighting for type hints as rioV8 suggested.

This is done by adding the following to my Vscode settings JSON file:

    "editor.semanticTokenColorCustomizations": {
      "rules": {
        "*.typeHint": {
          "foreground": "#bbbbbb",
          "fontStyle": "italic"
        },
        "class.typeHint.builtin": {
          "foreground": "#bbbbbb",
          "fontStyle": "italic"
        }
      }
    }
