Add contacts to Google Contacts' main Contacts list (not hidden) - google-apps-script

Question

I'm using the GAS code bellow to add a new contact into Google Contacts (https://contacts.google.com/):
var contact = ContactsApp.createContact('Bbbb', 'Cccc', 'mymail#mails.com').addUrl(ContactsApp.Field.WORK_WEBSITE, 'https://sites.google.com/site/...');
The code works perfectly but for a single detail: it adds the new contact to a hidden list and not to the main or visible «Contacts» list.
I know it works because when I use the lookup box to search for the newly created contact it's there, in the «Other contacts» list. I need it to be created in the main «Contacts» list from the beginning, otherwise I would have to do it manually using the «Add to contacts» icon with every contact created (I'm planning to add some thousands of contacts.)
Thanks.

Answer 1

For me, I have to add them to the ContactGroup named System Group: My Contacts.
function finishAddingContact(contact) {
var mainGroup = ContactsApp.getContactGroup("System Group: My Contacts");
if(mainGroup)
mainGroup.addContact(contact);
}
Note that getContactGroup(string) is an exact name match.
I recommend inspecting your ContactGroups for system groups, and then selecting the appropriate one from that list. It's probably the one with the most contacts in it:
function inspect() {
var groups = ContactsApp.getContactGroups();
for(var g = 0; g < groups.length; ++g) {
if(groups[g].isSystemGroup()) {
Logger.log(groups[g].getName() + ": " + groups[g].getContacts().length + " members, id=" + groups[g].getId());
}
}
}

Thanks a lot tehhwch.
I used your second code to get the right group ("System Group: My Contacts"), and then:
var contact = ContactsApp.createContact('Wunder', 'Bar', 'excellent#help.com');
var group = ContactsApp.getContactGroup("System Group: My Contacts");
group.addContact(contact);
It works, and the contact is immediately visible in my Android device.
