services.networking.gns3-server -> ubridge problems

Describe the bug

uBridge requires root access or the capability to interact with Ethernet and TAP adapters

Steps To Reproduce

Steps to reproduce the behavior:

I have setup gns3-server via the services module and gns3-gui via home-manager.

nixos-snowfall.home.extraOptions = {
  home.packages = with pkgs; [
    gns3-gui
  ];
};
# Add gns3-server as service.
services.gns3-server = {
  enable = true;
  ubridge = {
    enable = true;
  };
  auth = {
    enable = true;
    user = "gns3";
    passwordFile = "/path/to/password";
  };
};    
# Add current user to ubridge group.
users.users.${user.name}.extraGroups = [ "ubridge" ];

Setup a virtual device and 'Cloud' end device.
Try to add a link between the cloud device and the virtual device.

Expected behavior

I expect the link to be made, e.g. my user has access to ubridge.

Topology

Additional context

I am running the gns3-server and using the gns3-gui on the same machine. One is running via the nixos module and the other is via installing gns3-gui using home-manager.

# running via cli as normal user
ubridge       
uBridge version 0.9.18 running with libpcap version 1.10.4 (with TPACKET_V3)
iniparser: cannot open ubridge.ini

EDIT: Previously I was using this config and it worked.

    environment.systemPackages = with pkgs; [ gns3-server ubridge ];
    users.groups.ubridge = { };
    users.users.${user.name}.extraGroups = [ "ubridge" ];
    security.wrappers.ubridge = {
      source = "${pkgs.ubridge}/bin/ubridge";
      capabilities = "cap_net_admin,cap_net_raw=ep";
      owner = "root";
      group = "ubridge";
      permissions = "u+rx,g+rx,o+rx";
    };
