AWS IoT Core Rule Action to Timestream DB

Hello,

We are developing an application, that will potentially end up in our production environment in the coming months. We would like to use recently released Timestream DB for managing timeseries data for the application. But we have a problem.

Currently it is possible to set up an action via web UI console to push messages from IoT Core Rule to Timestream DB, but it is not possible to do so via Cloud Formation template according to these docs: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-iot-topicrule-action.html

Also I am confused by this: https://docs.aws.amazon.com/iot/latest/developerguide/timestream-rule-action.html
As it would seem as if it is allowed but after trying it couple weeks ago - it did not work.

Could we get this feature - defining IoT TopicRule action for timestream db in Cloud Formation template?

If yes, is there any ETA. that you could provide?
