You need to add your new module information in the Desktop Icon doctype
notice that this doctype is not searchable by a user, you can edit this and add administration role and add your doctype


You can add your icon to the icon field( you can use awesome font icons )
After adding it and refreshing, your module icon will appear on the Desk and the modules page
