go to parent directory in Picker files and maybe in grep

[zoomlin]

I have such hot key in my Telescope setup to go to parent directory on the fly. How i can implement it in Picker.files and may be in picker live_grep?

 ["<C-home>"] = function(prompt_bufnr)
            local current_picker = require("telescope.actions.state").get_current_picker(prompt_bufnr)
            -- cwd is only set if passed as telescope option
            local cwd = current_picker.cwd and tostring(current_picker.cwd) or vim.loop.cwd()
            local parent_dir = vim.fs.dirname(cwd)
            local function ivy(config)
              config = config or {}
              return require("telescope.themes").get_dropdown(vim.tbl_extend("keep", { previewer = true }, config))
            end
            require("telescope.actions").close(prompt_bufnr)
            require("telescope.builtin").find_files(ivy {
              previewer = false,
              theme = ivy,
              prompt_title = vim.fs.basename(parent_dir),
              cwd = parent_dir,
            })
          end,

  picker = {
    win = {
      input = {
        keys = {
          ["<C-home>"] = { "parent_dir", mode = { "n", "i" } },
        },
      },
    },
    actions = {
      parent_dir = function(p)
        p.opts.cwd = vim.fs.dirname(p.opts.cwd or vim.uv.cwd())
        p:find()
      end,
    },
  },
