Use native system icons in hyprland/workspaces

[Masber]

Dear waybar community,

I am new to waybar and hyprland but trying to configure my laptop.
I have installed wlr/taskbar module and looks pretty nice, then I installed hyprland/workspaces as below:

    "hyprland/workspaces": {
	"format": " <b>{icon}</b> {windows} ",
	"window-rewrite-default": "",
	"window-rewrite": {
	  "firefox": "󰈹",
	  "Alacritty": "󰞷",
	  "slack": "󰒱",
	  "thunderbird": "󰇮",
	  "spotify": "󰓇",
	  "org.keepassxc.KeePassXC": ""
	},
	"all-outputs": true,
        "on-scroll-up": "hyprctl dispatch workspace e+1",
        "on-scroll-down": "hyprctl dispatch workspace e-1",
        "on-click": "activate"
    },

The setup works and this is how it looks like

The thing is, the only way I could find to set icons in hyprland/workspaces is by using nerd fonts, I would like to use the "system default" icons as wlr/taskbar is using.

My question is:

Is there a way I can tell hyprland/workspaces to use "system default" icons instead of the nerd font ones?

thank you
