100-millisecond intervals

[PrefectSol]

In the July 2024 changelog, it is written about the availability of historical data at a 100 millisecond interval. How to use them? In timeseries periods, I don't see the time unit I need. An attempt to send a request to the server with a new 'period_id': "100MS\MILLIS\MILLISEC\MILLISECONDS" does not work. Is there any use case?
