How to make lsp client attach this buffer?

[rainzm]

Hi, I noticed that the filetype of copilot-chat is markdown, and I have two lsp client for markdown, of which rime-ls assists me in Chinese input.

For ordinary markdown files, they can be on attach, but not on copilot-chat's buffer. Is there any special configuration for this buffer? What should I do to get lsp client attach to this buffer?

I use the config in readme:

return {
  {
    "CopilotC-Nvim/CopilotChat.nvim",
    branch = "canary",
    dependencies = {
      { "zbirenbaum/copilot.lua" }, -- or github/copilot.vim
      { "nvim-lua/plenary.nvim" }, -- for curl, log wrapper
    },
    opts = {
      debug = true, -- Enable debugging
      -- See Configuration section for rest
    },
    -- See Commands section for default commands if you want to lazy load on them
  },
}
