Icons for the Doctypes and masters

Hi All,
I am using the ERPNext fromV4, That time the icons for the masters are supported and shown in the front end. But now its not showing in the front end. Now the doc are shown as blank, Is there any possibility of showing the icons in the front end.

you have to add the icons to ~apps/erpnext/config/desktop.py

Hi @jof2jc Thanks for reply
For modules I can set in that desktop.py. But I am asking for the Doctypes/Masters
