New doctype for Support module

I’m hoping for some direction on setting up a new doctype. I’ve duplicated the doctype (I called it “Supplier Issue”) and replaced “customer” with “supplier” throughout, but I want to add it to the Support menu … and I also need to test it to make sure it works – if I try to call up the new form, I get an error “Sorry, you are not permitted to view this page”, but the new doctype is accessible by the “Support Team” and I’m logged in as Administrator. I’d be grateful for any assistance.

Figured it out. After adding the new doctype, I navigated to frappe-bench/apps/erpnext/erpnext/config and modified to include this item in the menu. It works like a charm.
