Populate link with queried Values

My aim is to assign each ‘Trader’ (a Role) to a ‘Distributor’ (it’s also a Role). for this
I have made a SETUP doctype. It has Child Table. The child table has two link fields, both references the ‘UserRole’ table.

So, I want to populate all ‘Trader’ users in one link and all ‘Distributors’ in other link in the child table’s link fields.
How to custom script for this?

What have you tried so far? If you are stuck we can help. If you need someone to write a script, hire someone.

My script is,

frappe.ui.form.on('KD Assign', {
	refresh: function(frm) {

cur_frm.set_query("trader_link", "trader_to_kd", function(doc, cdt, cdn) {		
		filters: [
				['UserRole', 'parent', '=', "Trader"]

“trader_to_kd” is the child doctype,
“trader_link” is the link field in child doctype
“KD Assign” is the parent DocType.

Could you help me please.

So where are you stuck?
