[mcp1766]

Try to configure Whaler but no matter which file explorer to configure and also the command, it always launch Explore that I dont have.
This is my configuration in Telescope
`
",y",

     function()
        local telescope = require("telescope")
        --vim.keymap.set("n", "<leader>fw", function()
        telescope.extensions.whaler.whaler({
           directories = { "/home/mcp/tmp/", "/home/mcp/Projets/", "/home/mcp/notes/" },
           oneoff_directories = { "/home/mcp/.config/nvim" },
           auto_file_explorer = true,
           auto_cwd = true,
           file_explorer = "nvimtree",
           file_expplorer_config = {
              hidden = false,
              plugin_name = "nvim-tree",
              command = "NvimTreeOpen",
              prefix_dir = " ",
           },
           theme = {
              result_title = "Your selection..",
              layout_strategy = 'center',
              previewer = false,
              layout_config = {
                 height = 0.3,
                 width = 0.3,
              },
              sorting_strategy = "ascending",
              border = true,type (expected: string or dictionary)
 }
        })
        -- end)
     end,
     desc = "Open Whaler",
  },

`

And the error:
