How to enable completion in nui component buffer

[WizardStark]

One of the usecases I have would be greatly enhanced with the ability to have autocompletion in these buffers, for instance this is what I currently have using vim.ui.input:

	vim.ui.input({
		prompt = "Create: New session name",
		default = "",
		kind = "tabline",
	}, function(name_input)
		if name_input then
			vim.ui.input({
				prompt = "New session directory",
				default = "",
				completion = "dir",
				kind = "tabline",
			}, function(dir_input)
				if dir_input then
					on_success(name_input, dir_input)
				else
					on_cancel()
				end
			end)
		else
			on_cancel()
		end
	end)

And that nested input with directory completion saves me very much trouble.

Can this be done, and if so, how? Could even be using something like nvim-cmp using the path source, not sure what would be easier.

And then: boy does this library make it easy to create stunning ui's, its awesome.

I just needed directory completion, and so I used nvim's omnifunc with feedkeys to achieve this solution:

nui.text_input({
	border_label = "Dir",
	id = "dir",
	mappings = function()
		return {
			{
				mode = { "i" },
				key = "<Tab>",
				handler = function()
					local action = vim.api.nvim_replace_termcodes("<C-x><C-f>", true, false, true)
					vim.api.nvim_feedkeys(action, "i", false)
				end,
			},
		}
	end,
})

Still curious if there is another solution.
