Working great, thanks a lot for your contribution 🎉

Would you mind adding the new functionality to the README as well (config and default)? Assuming you have done that in your config, feel free to add an example mapping for this as well. I bet you're doing something cool, using the range from visual selection maybe? 😁

Hey no worries @debugloop , yep I'll do that. For some reason I cant find a clean way to do a keymap that reliably passes in the boundaries of the visual selection into telescope, this works but seems overkill:

    vim.api.nvim_create_user_command("TelescopeUndoVisual", function()
      -- Save the current view
      local view = vim.fn.winsaveview()

      -- Save the current mode
      local mode = vim.fn.mode()

      -- Temporarily switch to normal mode to ensure correct range capture
      vim.cmd("normal! \27")

      -- Get the first and last line numbers of the visual selection
      local start_line = vim.fn.line("'<")
      local end_line = vim.fn.line("'>")

      -- Call the function with the line range
      require("telescope").extensions.undo.undo({
        get_previewer = get_previewer,
        line_range = { start_line, end_line },
      })

      -- Restore the original view
      vim.fn.winrestview(view)

      -- If we were in visual mode, reselect the previous selection
      if mode == "v" or mode == "V" or mode == "\22" then
        vim.cmd("normal! gv")
      end
    end, { range = true })

Also nothing crazy just checking line numbers like I mentioned in the issue I raised haha

It should just be as simple as

      local start_line = vim.fn.line("'<")
      local end_line = vim.fn.line("'>")

then pass these in but for some reason they return 0 when used in a keymap? it works perfectly fine if I manually enter it while in a visual selection. Have you got any ideas?
