Google Shared Drive Push Notifications only Sending for Service Account Changes

Question

I would like to get push notifications anytime a file is added to our shared drive by any user.

I have a service account authenticated with the Google Drive API calling the changes.watch() method on the shared drive, and I successfully get notifications if the shared drive name or icon changes, a file is created by the service account, or if files are modified by any user so long as the service account created the file. However, I do not get any push notifications for files created on this shared drive by other users - even though the page token increases and calling changes.list() will show me the changes that all users made on the shared drive.

I have the shared drive shared with the service account, and the service account also has domain-wide delegation for the scope https://www.googleapis.com/auth/drive and uses that scope in the API call.

Any help would be greatly appreciated as I cannot figure out what I'm lacking to get push notifications for all changes on this shared drive. Below is my code related to authenticating and subscribing to change notifications.

import urllib

from google.oauth2.credentials import Credentials
from googleapiclient.discovery import build
from googleapiclient.errors import HttpError
from google.oauth2 import service_account

import uuid
from datetime import datetime

def get_service(api_name, api_version, scopes, key_file_location):
    credentials = service_account.Credentials.from_service_account_file(
    key_file_location)

    scoped_credentials = credentials.with_scopes(scopes)
    service = build(api_name, api_version, credentials=scoped_credentials)

    return service


def get_start_page_token(service):
    response = service.changes().getStartPageToken(
        driveId = "REDACTED",
        supportsAllDrives = True,
        supportsTeamDrives = True
        ).execute()
    startPageToken = response.get("startPageToken")
    print(F'Start token: {startPageToken}')
    return startPageToken

def subscribe_changes(service):
    channel_id = str(uuid.uuid4())

    body = {
        "id": channel_id,
        "type": "web_hook",
        "address": "https://REDACTED"
    }

    response = service.changes().watch(
          body=body, 
          pageToken = get_start_page_token(service),
          includeItemsFromAllDrives = True,
          supportsAllDrives = True,
          supportsTeamDrives = True,
          driveId = "REDACTED"
        ).execute()

    ts = int(response['expiration'])
    print("Expiration in UTC: " + datetime.utcfromtimestamp(ts / 1000).strftime('%Y-%m-%d %H:%M:%S'))
    print(response)
    return channel_id



# Define the auth scopes to request.
scope = 'https://www.googleapis.com/auth/drive'
key_file_location = 'credentials.json'

try:
    # Authenticate and construct service.
    service = get_service(
        api_name='drive',
        api_version='v3',
        scopes=[scope],
        key_file_location=key_file_location)

except HttpError as error:
    print(f'An error occurred: {error}')


# subscribe to changes
channel_id = subscribe_changes(service)
print(f"Channel Id: {channel_id}")
