How to use trace?

[shartf]

Hello, I am trying to trace a function but cannot get trace results. Here is my config part:

  "monkoose/nvlime",
  ft = { "lisp" },

  dependencies = {
    "monkoose/parsley",
  },
  init = function()
    vim.g.nvlime_config = {
      leader = "<leader>i",
      implementation = "sbcl",
      contribs = {
        "SWANK-ASDF",
        "SWANK-PACKAGE-FU",
        "SWANK-PRESENTATIONS",
        "SWANK-FANCY-INSPECTOR",
        "SWANK-C-P-C",
        "SWANK-ARGLISTS",
        "SWANK-REPL",
        "SWANK-FUZZY",
        "SWANK-TRACE-DIALOG",
      },
      user_contrib_initializers = nil,
      autodoc = {
        enabled = false,
        max_level = 5,
        max_lines = 50,
      },
      main_window = {
        position = "right",
        size = "",
      },
      floating_window = {
        border = "single",
        scroll_step = 3,
      },
      cmp = { enabled = true },
      arglist = { enabled = true },
    }
  end,

I can load the file, let us say

(defun fibonacci (n &optional (a 0) (b 1) (acc ()))
  (if (zerop n)
      (nreverse acc)
      (fibonacci (1- n) b (+ a b) (cons a acc)))) <--- SET TRACE HERE WITH <leader>tt

(fibonacci 5) <--- eval with <leader>ii/ie

But I never see the trace dialog, actually. Though I get the results of evaluation just fine. If I set (trace fibonacci) in code I get the actual trace:

  0: (FIBONACCI 5)
    1: (FIBONACCI 4 1 1 (0))
      2: (FIBONACCI 3 1 2 (1 0))
        3: (FIBONACCI 2 2 3 (1 1 0))
          4: (FIBONACCI 1 3 5 (2 1 1 0))
            5: (FIBONACCI 0 5 8 (3 2 1 1 0))
            5: FIBONACCI returned (0 1 1 2 3)
          4: FIBONACCI returned (0 1 1 2 3)
        3: FIBONACCI returned (0 1 1 2 3)
      2: FIBONACCI returned (0 1 1 2 3)
    1: FIBONACCI returned (0 1 1 2 3)
  0: FIBONACCI returned (0 1 1 2 3)
