Cant create custom labels filter

[Facundo]

Hello. I am trying to follow this tutorial but with only two levels instead of three. I need to implement the same behavior that when you set the items to be included in an adgroup by selecting the custom labels. 

# [START add_shopping_product_listing_group_tree]

def create_listing_group(client, customer_id, ad_group_id, replace_existing_tree):

"""Adds a shopping listing group tree to a shopping ad group.

Args:

client: An initialized Google Ads client.

customer_id: The Google Ads customer ID.

ad_group_id: The ad group ID to which the node will be added.

replace_existing_tree: Boolean, whether to replace the existing listing

group tree on the ad group. Defaults to false.

"""

# Get the AdGroupCriterionService client.

ad_group_criterion_service = client.get_service("AdGroupCriterionService")

# on the ad group. The example will throw a LISTING_GROUP_ALREADY_EXISTS

# error if a listing group tree already exists and this option is not

# set to true.

That there are fields, that im not sending, that it is missing the others.
