How to use semanticTokens.combinedModifiers rightly

[wangrongwei]

I see 'semanticTokens.combinedModifiers' seems can help me highlight local variable in function scope (I'm not sure this is semanticTokens.combinedModifiers wana to do), So, I try it, but it doesn't work:

This is my coc-setting.json

{
  "languageserver": {
  },
  "suggest.floatConfig": {
    "border": true,
    "borderhighlight": "CocBorder"
  },
  "semanticTokens.filetypes": ["c"],
  "semanticTokens.enable": true,
  "semanticTokens.highlightPriority": 3000,
  "semanticTokens.combinedModifiers": ["functionScope"],
  "[c]": {
    "semanticTokens.enable": true,
    "semanticTokens.highlightPriority": 3000,
    "semanticTokens.combinedModifiers": ["functionScope"]
  },
>-"clangd.semanticHighlighting": true,
  "coc.preferences.semanticTokensHighlights": false
}

and CocInfo output：

## versions

vim version: VIM - Vi IMproved 9.1 9010825
node version: v23.1.0

This is output of CocCommand semanticTokens.checkCurrent

Tokens types that current Language Server supported:

- CocSemTypeVariable
- CocSemTypeParameter
- CocSemTypeFunction
- CocSemTypeMethod
- CocSemTypeProperty
- CocSemTypeClass
- CocSemTypeInterface
- CocSemTypeEnum
- CocSemTypeEnumMember
- CocSemTypeType
- CocSemTypeUnknown
- CocSemTypeNamespace
- CocSemTypeTypeParameter
- CocSemTypeConcept
- CocSemTypeMacro
- CocSemTypeModifier
- CocSemTypeOperator
- CocSemTypeComment

It seems that current Language Server not support CocSemTypeModVariableFunctionScope? or I need to update my clang?

Thanks for any comments.

It has been solved by restart clangd (maybe).
