Custom App with defined custom DocType: Not showing in Desk?

I created a custom app and I’m trying to define a Custom DocType.

I placed the new_doctype.json file in frappe-bench/myapp/myapp/doctype/newdoctype.json

I installed the app on the site, and bench migrate (though I don’t think I needed to).

The app shows that it’s installed in the About menu, however the DocType I defined isn’t showing up in desk…

I tried clearing both the browser and the bench cache, and even restarted the server.

Is there something else I have to do to define a DocType in a custom app?

My doctype.json is as follows

{
 "name": "Geotools Settings",
 "doctype": "DocType",
 "is_single": 1,
"module":"Integrations",
 "fields": [
  {
   "fieldname": "google_js_api_key",
   "fieldtype": "Password",
   "label": "Google Javascript API Key"
  }
 ]
}
