MSSQL -- calling Oracle Package ?

How you have any examples on how I change the below YELLOW #2 so my Oracle PROJECT_TRANSACTION_API.NEW__ package works via MSSQL Server Management Studio ?
-----------------------------------------------------------------------------------------
#1 = Below works in MSSQL Server Management Studio

(SELECT * FROM OPENQUERY(IFSTEST,'Select SABR1APP.Supplier_API.Get_Vendor_name(''CONOP'') from dual'))
-----------------------------------------------------------------------------------------
#2 = Below works in Oracle SQL Developer
