Cannot change style of annotation in LazyVim

[G00Z-G00Z]

I'm trying to change the documentation style in lazy vim using their LazyVim.extras using their documentation. However It does not seem to be working. I do not know if its a problem with LazyVim itself. Here is the snippet that does not work:

return {
  "danymat/neogen",
  dependencies = LazyVim.has("mini.snippets") and { "mini.snippets" } or {},
  cmd = "Neogen",
  keys = {
    {
      "<leader>cn",
      function()
        require("neogen").generate()
      end,
      desc = "Generate Annotations (Neogen)",
    },
  },
  opts = function(_, opts)
    if opts.snippet_engine ~= nil then
      return
    end

    local map = {
      ["LuaSnip"] = "luasnip",
      ["mini.snippets"] = "mini",
      ["nvim-snippy"] = "snippy",
      ["vim-vsnip"] = "vsnip",
    }

    for plugin, engine in pairs(map) do
      if LazyVim.has(plugin) then
        opts.snippet_engine = engine
        return
      end
    end

    if vim.snippet then
      opts.snippet_engine = "nvim"
    end

    -- Does not seem to work
    opts.languages = {
      python = {
        template = {
          annotation_convention = "google", -- for a full list of annotation_conventions, see supported-languages below,
        },
      },
    }
  end,
}

I tried putting the configuration in the table, but it does not seem to work
