Changing telescope config not applied

[snikoletopoulos]

I'm using lazy.nvim. I change the undo configuration in the opts settings of telescope (ex. use_delta & mappings). However, no change are applied when I use the plugin.

Am I doing something wrong here?

telescope-undo.nvim config:

{
  "debugloop/telescope-undo.nvim",
  lazy = true,
  specs = {
    {
      "nvim-telescope/telescope.nvim",
      dependencies = {
        "debugloop/telescope-undo.nvim",
        {
          "AstroNvim/astrocore",
          opts = {
            mappings = {
              n = {
                ["<Leader>fu"] = { "<Cmd>Telescope undo<CR>", desc = "Find undos" },
              },
            },
          },
        },
      },
      opts = function() require("telescope").load_extension "undo" end,
    },
  },
}

telescope config:

{
  "nvim-telescope/telescope.nvim",
  opts = {
    extensions = {
      undo = {
        use_delta = false,
      },
    },
  },
}
