Help: Multiple ascii art headers in dashboard

[EmilianoAncer]

I have a function with multiple ascii arts, and the function simply picks one at random, problem is I cant get it to print on the dashboard.

    local function pick_header()
        local function pick_color()
	        local colors = { "String", "Identifier", "Keyword", "Number" }
	        return colors[math.random(#colors)]
        end
        -- Set header
        local logo = {
	        {
		     (Ascii art)
	        },
	        {
                       (Other ascii art)
	        },
        } 

local function pickLogo(logoLength)
	return math.random(1, logoLength)
end
return logo[pickLogo(#logo)]
-- dashboard.section.header.opts.hl = pick_color()
    end
    return {
        "folke/snacks.nvim",
        priority = 1000,
        lazy = false,
        ---@type snacks.Config
        opts = {
	        bigfile = { enabled = true },
	        dashboard = {
		        header = pick_header(),
		        sections = {
			        { section = "header" },
			        {
				        pane = 2,
				        section = "terminal",
				        cmd = "colorscript -e square",
				        height = 7,
				        padding = 1,
			        },
			        { section = "keys", gap = 1, padding = 1 },
			        { pane = 2, icon = " ", title = "Recent Files", section = "recent_files", indent = 2, padding = 1 },
			        { pane = 2, icon = " ", title = "Projects", section = "projects", indent = 2, padding = 1 },
			        {
				        pane = 2,
				        icon = " ",
				        title = "Git Status",
				        section = "terminal",
				        enabled = function()
					        return Snacks.git.get_root() ~= nil
				        end,
				        cmd = "git status --short --branch --renames",
				        height = 5,
				        padding = 1,
				        ttl = 5 * 60,
				        indent = 3,
			        },
			        { section = "startup" },
		        },
	        },

I am trying to call the function from header, and just using the header section, but this does not seem to work.
This might be a stupid question, I'm new to Neovim and Lua.
