How to bring a new module to the desktop?

I create a new module in Module Def called ‘new’. then add a new module in the desktop.py file, created a file in directory with the module name new.py
made a bench migrate command in the console,
the new module is not displayed on the desktop, but if you go through the browser
https: // mysite / desk # modules / new
then the module is displayed.
