How to use same keybindings from terminal to toggle the terminal

[luisiacc]

I have this config

{
    "folke/snacks.nvim",
    priority = 1000,
    lazy = false,
    opts = {
      -- your configuration comes here
      -- or leave it empty to use the default settings
      -- refer to the configuration section below
    },
    keys = {
      {
        "<C-y>",
        function()
          Snacks.terminal.toggle()
        end,
        desc = "Terminal",
      },
    },
  }

To toggle the terminal I use C-y, I want to press C-y to also close the terminal when I'm inside it, but this does not seem to work, I have to press double in order to be able to press C-y to toggle it.

add mode = {"n", "t"}, like in the example
