Hyprland workspaces how to format with icon and set id as fallback

# NIX
      "wlr/workspaces" = {
        format = "<span font='13'>{icon}</span>";
        format-icons = {
          "1" = "";
          "2" = "";
        };
        active-only = false;
        on-click = "activate";
      };

When I was using wlr/workspaces I had this behavior where I only defined the first 2-3 icons and all other workspaces were displayed with a number (id). When I updated my system and probably updated hyprland, waybar, etc, my workspaces were no longer showing, so I switched to hyprland/workspaces module and now I don't have the desired behavior. With the same setup I've shown, all my subsequent workspaces, starting with 3 and inclusive, are marked with the same icon as the last icon defined (in my case the second one). Something like format="{id}{icon}" is really ugly. I want to set the {id} format as a fallback if there is no icon defined. Is it possible with hyprland module? It was possible with wlr module.
