People API - Update Contacts - How to update individual fields instead of all (e.g. phoneNumbers) using GAS

Question

in order to update my contacts phone numbers, I am using People API with following code:

function updateContact(contactRn, contactEtag, contactPhone){

  var bodyRequest = {
    "resourceName": contactRn,
    "etag": contactEtag,

    "phoneNumbers": [{
      'value': contactPhone,
      'Type': 'googleVoice' }]
   };
    
   People.People.updateContact(bodyRequest, contactRn, {updatePersonFields: "phoneNumbers"});
 }

It works. It updates the phone number of the contact.

Unfortunately, it also overwrites all other phone numbers associated with this contact, which means it deletes them.

Can you tell me how to update specific phone numbers only (like the contacts google voice number), using GAS?

Thanks, Flo

Allright, I decided to try the simplest thing, and just add more itens to the array, and what you know? It worked for me.

        function updateContact(contactRn, contactEtag, contactPhone){
  var bodyRequest = {
    "resourceName": contactRn,
    "etag": contactEtag,
    "phoneNumbers": [{'value': contactPhone, 'type': 'googleVoice' },
    {'value': anotherPhone,'type': 'workphone' },
    {'value': thirdPhone,'type': 'homephone' }]
   };
    
   People.People.updateContact(bodyRequest, contactRn, {updatePersonFields: "phoneNumbers"});
 }

My contact now has updated all his 3 phone numbers on google contacts
