PRINT VALUE OF OBJECT || PLSQL

Question

I want to see values of object as output.

My PL/SQL Code:

CREATE OR REPLACE PROCEDURE XPROC( p_val       IN     xxx%TYPE DEFAULT NULL,
      p_debt_receivable_out      OUT SYS_REFCURSOR)
IS
invoice_det get_debt_type;

BEGIN

insert into tmp_invoice_det  xxxxxxxxx;

select get_debt_obj(INVOICE_NUMBER,
INVOICE_DATE,
INVOICE_PERIOD,
DUE_AMOUNT,
DUE_DATE,
INVOICE_STATUS,
INVOICE_ADDRESS) bulk collect into
invoice_det from  tmp_invoice_det;

OPEN p_debt_receivable_out FOR
select total_debt,TOTAL_RECEIVABLE,invoice_det as invoice_detail from xxxxxxxxx;
  
END;  

How I call:

set serveroutput on
variable  result refcursor
DECLARE
p_val VARCHAR2(144);
 
BEGIN
  p_val:= ‘12345’;

XPROC(p_val, :result);

END;
/

print result;

OUTPUT:

TOTAL_DEBT	TOTAL_RECEIVABLE	INVOICE_DETAIL
159	0	GET_DEBT_TYPE([CDR_INQUIRY.GET_DEBT_OBJ],[CDR_INQUIRY.GET_DEBT_OBJ],[CDR_INQUIRY.GET_DEBT_OBJ])

EXPECTED OUTPUT:

TOTAL_DEBT	TOTAL_RECEIVABLE	INVOICE_DETAIL
159	0	INVOICE_DETAIL: value , INVOICE_DATE: value ,INVOICE_PERIOD: value, ......
