Best way to 'toggle' Dashboard view?

[JxJxxJxJ]

I had a command to do this with Dashboard.nvim but I can't make it work with snacks

My keymaps:

vim.api.nvim_set_keymap('n', '<Leader>;', ':lua ToggleDashboard()<CR>', { noremap = true, silent = true })

function ToggleDashboard()
  -- Si aun nunca fui a un dashboard
  if original_file == '' then
    -- Guarda el archivo actual y abre el dashboard
    original_file = vim.fn.expand '%:p'
    Snacks.dashboard() -- Usar un comando de lua `:lua ... "`
  else -- Hay algo en original file, es decir estoy en un dashboard
    -- Vuelve al archivo original
    vim.cmd('edit ' .. original_file)
    original_file = '' -- Y borro para poder usarla de nuevo
  end
end

It successfully goes to the dashboard but can't go back to the saved buffer, it seems it gets overriden by dashboard or something?
