How to highlight every element of the capture to replicate tree-sitter-comment's highlighting?

tree-sitter-comment

todo-comments

How can I recolor the commenter's name and the braces? The highlight color seems to recolor the entire capture.

My config

{
  highlight = {
    pattern = ".*<((KEYWORDS)%(\\(.{-1,}\\))?):",
    keyword = "fg",
    after  = "",
  }
}
