In which version of Oculus Interaction SDK will the Direct Touch function be updated and supported?

I saw that the official website advertised that Oculus Interaction V50 SDK had support of Direct Touch technical functions, but now we have updated the SDK version of V50, and no Direct Touch related functions have been found. Check the official website of the V50 version of the update does not have a description of the Direct Touch function. In which version of Oculus Interaction SDK will the Direct Touch function be updated and supported? Thanks!
