How to enable indent-blankline scope lines

[vabatta]

As per the images shown on https://github.com/lukas-reineke/indent-blankline.nvim#multiple-indent-colors and the integration within Catppuccin, how do I make the scope lines to appear?

In catppuccin/nvim loaded in LazyVim:

integrations = {
  indent_blankline = {
    enabled = true,
    colored_indent_levels = false,
  },
}

and in lukas-reineke/indent-blankline.nvim:

scope = {
  enabled = true,
  show_exact_scope = true,
},
