I can't find usage of scroll-api.
Do you have any guide or md file to show scroll api usage?

@frank-belldev and anyone else looking...

from intercom.client import Client
intercom_client = Client(personal_access_token='[YOUR_ACCESS_TOKEN]')
for intercom_user in intercom_client.users.scroll():
    print(intercom_user.id)

It automatically fetches the pages of content for you in the background.
