How to add Notes in Notes Section (Not which is part of fields) in Lead using SDK

I have been following this reference to update and post records
https://www.zoho.com/crm/developer/docs/nodejs-sdk/module-samples.html?src=update_records

My SDK Version is 0.0.20

I want to be able to add notes to the Lead, but couldn't find a sample in this, what scope, or how to do this ?
