blink.cmp doesn't work but I don't know why...

[Jaehaks]

I am Winodws 10 user, and set the blink.cmp configuration like this
But there are no any error about this, and just don't show the completion menu with any trigger.
What I missed?

return {
  'saghen/blink.cmp',
  version = '1.*',
  event = 'InsertEnter',
  opts = {
    keymap = { preset = 'default' },
    appearance = { nerd_font_variant = 'mono' },
    completion = {
      keyword = {
        range = 'prefix',
      },
      documentation = {
        auto_show = true
      },
    },
    sources = {
      default = {'lsp', 'path', 'snippets', 'buffer'},
      per_filetype = {
        lua = {'lsp', 'buffer'}
      },
      min_keyword_length = 0,
    },
    -- fuzzy = {
      -- 	implementation = 'prefer_rust_with_warning'
      -- }
    },
    opts_extend = {
      'sources.default'
    },
    config = function ()
      local capabilities = require('blink.cmp').get_lsp_capabilities()
      vim.lsp.config['*'] = {
        capabilities = capabilities,
      }
    end

  }

the healthcheckh is this

==============================================================================

I missed important thing...
If I want ot add config field, setup() must be called in config field

config = function ()
  require('blink.cmp').setup(opts)  
  local capabilities = require('blink.cmp').get_lsp_capabilities()
    vim.lsp.config['*'] = {
      capabilities = capabilities,
  }
end

Fyi the capabilities are automatically setup with vim.lsp.config, so this shouldn't be necessary: https://github.com/Saghen/blink.cmp/blob/main/plugin/blink-cmp.lua#L1

I didn't recognize that, Thanks!
