How do I make LSP progress background transparent?

[Alienover]

require("noice").setup({ 
  lsp = {
    progress = {
      enabled = true,
  }
})

Currently, the background from percentage to client name is Black. Wanna ask whether there's a highlight group I can update to make the background transparent?

Actually, I can get the LSP progress with transparent background by using fidget.nvim. But I am curious about whether Noice can do that. If so, I don't have to install one more plugin.

FYI, my color scheme is catppuccin-mocha.
