Just curious what the status on this is? What's the expected time line, etc?

Basically I really want to use this feature in the next week or 2, but even if I have an idea for the timeline I can create the resource manually and import it once the feature is available.

And thanks for the work on this, its much appreciated 🙏

Our goal is to release this as soon as we can make our next release, but there's some SDK problems blocking that release happening (and this resource) so we don't have a timeline. I'd go ahead and create it manually for now.
