Undo mapping in lazy Vim

Two ways to undo current mappings, some mapping come with plugin setup and others are native LazyVim keymaps. To find which is which use :nmap <Space> (or :vmap g for different mode) and search for the keymap there.

If the key mapping is from a plugin:

-- In plugins.lua
{
  "plugin.nvim",
  keys = {
    "lhs", false
  }
}

If the plugin is a default LazyVim:

vim.keymap.del("n", "lhs")
