Is the process of adding module change?

Frappe Framework
1

I have been adding module in frappe successfully but now my new module will not appear in the desktop. This is my step that I follow.

  1. Create a Module entry in Module Def.

  2. Add entry in desktop.py

    -- coding: utf-8 --

    from future import unicode_literals
    from frappe import _

    def get_data():
        return {
            "Wela": {
                "color": "grey",
                "icon": "octicon octicon-file-directory",
                "type": "module",
                "label": _("Wela")
            },
            "Grading": {
                "color": "#3498db",
                "icon": "octicon octicon-repo",
                "type": "module"
            },
            "School Setup": {
                "color": "#16a085",
                "icon": "octicon octicon-tools",
                "type": "module"
            },
            "Disciplinary Notes": {
                "color": "#1abc9c",
                "icon": "octicon octicon-pencil",
                "type": "module"
            },
            "Registration": {
                "color": "#77216F",
                "icon": "octicon octicon-organization",
                "type": "module"
            },
            "ID Management": {
                "color": "#77216A",
                "icon": "octicon octicon-link",
                "type": "module"
            }
        }

'3. create id_management.py in config folder.

from __future__ import unicode_literals
from frappe import _


def get_data():
    return [
        {
            "label": _("Document"),
            "icon": "icon-star",
            "items": [
                {
                    "type": "doctype",
                    "name": "RFID Tagging",
                    "description": _("RFID Tagging")
                }
            ]
        }
    ]

My new module cannot be seen in the menu Set My Desktop Icons
My new module is not present in the Module access in the User Setting.

Any idea what I missed? or the process of adding module change?
