how to change Contact record owner using Deluge Function?

let say I have CONTACT_ID (the ID of the record) and also USER_ID ( the new owner ID), I want to change the owner of that record programmatically using Zoho CRM function (Deluge). I am confused what method do I have to use, I have tried to use the code I write by myself below but it doesn't work

CONTACT_ID = 5660400000001065159;
USER_ID = 5660400000000531165;

contact = zoho.crm.getRecordById("Contacts",CONTACT_ID);
owner = {"name":"Sales 2","id": USER_ID,"email":"myemail@yahoo.com"};
update = {"Owner":owner};
zoho.crm.updateRecord("Contacs",CONTACT_ID,update);

Could you please at least give a guidence how to update the record owner using function? I want to use the function in my workflow rules
