In Desk/desktop.py/module.py, how to create a hyperlink to portal page?

I’ve successfully created a portal page at https://localhost:8000/draft_stores (as described here: https://frappe.io/docs/user/en/portal-pages). Now my problem is: how to create a hyperlink to that portal page?

I checked https://frappe.io/docs/user/en/guides/app-development/adding-module-icons-on-desktop but it only gives information on how to created doctype menu items.

I’ve tried to create in apps/library_management/library_management/config/library_management.py :

def get_data():
    return [
      {
        "label":_("Library"),
        "icon": "octicon octicon-briefcase",
        "items": [
            {
              "type": "page",
              "name": "draft_stores",
              "label": _("Calon Warung"),
              "icon": "fa fa-bar-chart",
              "onboard": 1,
            }, 

I also tried "type": "link" both in library_management.py and desktop.py and none works.
