Can't insert files, no file selection pops up

[armanschwarz]

My config:

return {
  "olimorris/codecompanion.nvim",
  commit = "3c1b2e3",
  dependencies = {
    "nvim-lua/plenary.nvim",
    {
      "nvim-treesitter/nvim-treesitter",
      build = ":TSUpdate",
      config = function()
        require("nvim-treesitter.configs").setup({
          ensure_installed = { "lua", "markdown", "markdown_inline", "yaml" },
          highlight = { enable = true },
        })
      end,
    },
  },
  opts = {
    default_adapter = "fast",
    adapters = { ... },
    interactions = {
      chat = {
        adapter = "fast",
        slash_commands = {
          ["file"] = {
            opts = {
              provider = "default", -- tried "telescope" as well
            },
          },
        },
      },
    },
  },
}

When I type "/file" I see the cmp options picker come up, but when I hit enter, or select the /file option from the dropdown and press or space nothing happens, it just enters to the next line. I have no mappings on so I'm a bit stumped... How can I make the file picker work? I'm using nvim v0.11.3.

Adding this dependency seems to have fixed it:

    {
      "saghen/blink.cmp",
      lazy = false,
      version = "*",
      opts = {
        keymap = {
          preset = "enter",
          ["<S-Tab>"] = { "select_prev", "fallback" },
          ["<Tab>"] = { "select_next", "fallback" },
        },
        cmdline = { sources = { "cmdline" } },
        sources = {
          default = { "codecompanion" },
        },
      },
    },

The Getting Started guide and Chat Buffer Config cover this. If you don't have either blink, cmp or coc installed you can use native Neovim completions.
