get https://{server}/api/v2.1/admin/statistics/auto-rules/
The system documents automation rules by single users (users who are not in any teams) or by teams. In most cases, especially on cloud.seatable.io, there're no such scenario that a single user could exist, so the usage of the param is_user as true is seldom. As this API request is developed in SeaTable 2.4.2 which came out in September 2021, automation rules statistics before September 2021 could not be correctly summarized with this call.
