How to set tokenColors in monaco-editor?

[durianwaffle]

Hi Langium Community,

I am trying to set customized color for variables.
I tried the scope below, but it doesn't work.

"scope": [
              "variable",
              "variable.other",
              "variable.language",
              "meta.definition.variable.name",
              "variable.other.enummember",
              "entity.name.variable",
              "support.variable"
          ]

For functions, the scope below doesn't work

"scope": [
                "entity.name.function",
                "entity.name.function.preprocessor",
                "meta.function",
                "entity.name.function.parameter",
                "parameter"
            ],

The default VS theme: https://gist.github.com/scottmwyant/2dc64ff4315ba9e2c374fb329b399820

I am wondering how can I get the scope name for a given token? For example parameter in functions, function.
