Nvim-cmp not being transparent

[alexmllo]

Hi, I am trying to set my nvim-cmp windows to be semi-transparent like this:

This is how my current set up looks like:

My configuration on top of lazyvim:
Colorscheme:

return {
    {
        "LazyVim/LazyVim",
        opts = { colorscheme = "catppuccin" },
    },
    {
        "rasulomaroff/reactive.nvim",
        optional = true,
        opts = {
            load = { "catppuccin-mocha-cursor", "catppuccin-mocha-cursorline" },
        },
    },

    {
        "catppuccin/nvim",

        opts = {
            transparent_background = true,
            integrations = {
                lsp_trouble = true,
                dadbod_ui = true,
                octo = true,
            },
        },
    },
}

nvim-cmp:

return {
    {
        "hrsh7th/nvim-cmp",
        dependencies = {
            "hrsh7th/cmp-emoji",
        },
        opts = function(_, opts)
            table.insert(opts.sources, { name = "emoji" })
            vim.api.nvim_set_hl(0, "Normal", { bg = "none" })
            vim.api.nvim_set_hl(0, "NormalFloat", { bg = "none" })
            opts.window = {
                completion = {
                    border = "rounded",
                    winhighlight = "Normal:Normal,FloatBorder:Normal,CursorLine:Visual,Search:None",
                    scrollbar = false,
                },
                documentation = {
                    border = "rounded",
                    winhighlight = "Normal:Normal,FloatBorder:Normal,CursorLine:Visual,Search:None",
                    scrollbar = false,
                },
                error
            }
        end,
    },
}
