Issue with supervisory app


About a month ago I had received a link containing the guidance on building the supervisory app in CommCare. However, the same page is showing an error message and it says that these features are no longer supported in CommCare.
Kindly guide me with the same on how to build the supervisory app.

I have attached the link below.
