UBUS notifications are not received by non-root user

For Developers

I am trying to use the ubus ACL feature with ubusd and provided an ACL file at /usr/share/acl.d location as below-

{
  "user": "alok",
  "access": {
    "module1": {
      "methods": [
        "get_dump_list"
      ]
    },
    "module2": {
      "methods": [
        "get_info"
      ]
    }
  },
  "send": [
    "module1",
    "module2"
  ],
  "subscribe": [
    "module1",
    "module2"
  ],
  "publish": [
    "module1",
    "module2"
  ]
}

My Setup-
ubusd -> root
myModule1 -> non_root_user --> sends notification as signal1
myModule2 -> non_root_user --> signal1 not received
While the signal1 is received at ubus monitor and methods of myModule1 I am able to call from root as well as from myModule2.
Any idea what I am missing?
