Thanks for flagging. I’ve confirmed that the docs listed those parameters that weren’t live yet. I’ve just submitted an update to the docs to match current API behavior.
I don’t have an ETA on when the additional parameters will be available. If you are seeing any issues from the engine/Studio side, please feel free to open a new report and it’ll be triaged accordingly.
