How to map a contact from CRM to an "integrated field" in Projects with a function?

Hi!

I have CRM and Projects integrated, and a function that creates a project automatically when a deal is modified in CRM. The function maps several fields from the CRM to Projects.

I was wondering how to map the contact related to the Deal to an "integrated field" I added to Zoho Projects.

Do I have to create a map with the contact ID?

I just need the snippet that maps the CRM field with the integrated field in projects.
