Can't generate my own footer with require("lazy").stats()

[cactusnix]

When I call require("lazy").stats() to get startup time, but it always show 0.
I think it might be due to startup time is generated till UIEnter.
So I don't know how to make my own footer that shows startup time of lazy.nvim.
Here is my code:

config = function(_, opts)
  local stats = require("lazy").stats()
  local footer = {
    "",
    "",
    "",
    "󰔚 "
    .. stats.startuptime
    .. " / 󰏋 "
    .. stats.loaded
    .. " / 󱑥 "
    .. stats.count,
}
  require("dashboard").setup(
    vim.tbl_deep_extend("force", opts, { config = { footer = footer } })
  )
end,
