If you open a terminal in another neovim instance in the same directory, then run toggle the remote terminal shows up in the selector picker. When selecting it though, nothing seems to be happening.

3. Open another neovim instance in the same directory, and run toggle to open the same temrinal type
4. Picker will open showing the remote terminal

require("lazy.minit").repro({
  spec = {
    { "folke/sidekick.nvim", opts = {} },
    -- add any other plugins here
  },
})
