Copilot suggestions not appearing in the suggestion box

[Habush]

Hi,

I'm trying to get GitHub Copilot to work with blink.cmp. I'm using the blink-cmp-copilot plugin and followed the setup in the readme. I installed Copilot via copilot.lua and created an autocmp.lua script that configures blink to use copilot. However, typing in a source file, copilot suggestions don't show in the drop-down and I only see suggestions from LSP servers. Here is the content of autocmp.lua script:

return {
  {
    "saghen/blink.cmp",
    dependencies = {
      "L3MON4D3/LuaSnip", -- For snippet expansion (if needed)
      -- Add any additional dependencies as recommended in the blink.cmp docs.
      {
        "fang2hou/blink-copilot",

        opts = {
          max_completions = 3,
          max_attempts = 4,
          kind = "Copilot",
          debounce = 750, ---@type integer | false
          auto_refresh = {
            backward = true,
            forward = true,
          },
        },
      },
    },
    config = function()
      require("blink.cmp").setup({
        -- You can configure general settings here.
        -- For example, the documentation shows configuration of snippet expansion,
        -- key mappings, and source registration.
        keymap = {
          -- set to 'none' to disable the 'default' preset
          preset = "none",

          ["<C-space>"] = { "show", "show_documentation", "hide_documentation" },

          ["<Tab>"] = {
            function(cmp)
              local completion_list = require("blink.cmp.completion.list")
              vim.schedule(function()
                completion_list.accept({
                  index = completion_list.selected_item_idx or 1,
                })
              end)
              return true
            end,
          },

          ["<C-b>"] = { "scroll_documentation_up", "fallback" },
          ["<C-d>"] = { "scroll_documentation_down", "fallback" },

          ["<C-k>"] = { "show_signature", "hide_signature", "fallback" },
        },
        completion = {
          menu = {
            auto_show = function(ctx)
              return ctx.mode ~= "cmdline" or not vim.tbl_contains({ "/", "?" }, vim.fn.getcmdtype())
            end,

            },
            transform_items = function(_, items)
              local CompletionItemKind = require("blink.cmp.types").CompletionItemKind
              local kind_idx = #CompletionItemKind + 1
              CompletionItemKind[kind_idx] = "Copilot"
              for _, item in ipairs(items) do
                item.kind = kind_idx

        Event = "󱐋",
        Operator = "󰪚",
        TypeParameter = "󰬛",
      },
    },
  },
  {
    "neovim/nvim-lspconfig",
    dependencies = {
      "williamboman/mason.nvim",

      lsp.pylsp.setup({
        capabilities = blink_cmp,
      })
    end,
  },
}

As suggested in blink-cmp-copilot readme, I disabled copilot.lua's suggestion and panel modules. I also added copilot as a source to blink-cmp. However, I can't get copilot suggestions to show up in autocomplete window. How can I fix this? Thanks.
