Does "per document monitor" also support "action throttling"?

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):
2.11.1 docker
Microsoft Edge

Describe the issue:
Is it possible to configure “action throttling” also for “per document monitor”?
or something similar?

It seems that the UI doesn’t support action throttling for per document monitor, but actually we can achieve that by calling the update monitor API:

PUT _plugins/_alerting/monitors/<monitor_id>
{
          ...
           "throttle_enabled": true,
            "throttle": {
              "value": 27,
              "unit": "MINUTES"
            },
          ...
}

It is updated, but it has no effect whatsoever.
Or did it work for you?
