I'm watching the video What's Happening in SideFX Labs | Danicka Oglesby | GDC HIVE 2023 and the presenter mentions there are labs VEX files named sidefxlabs_data.h and sidefxlabs_math.h under vex/include. I do not see them for Houdini version Houdini19.5.605. Are these files available yet? If so where are they located? I'm unable to find files with similar names in the Houdini install directory.

They are in labs package folder
Side Effects Software\sidefx_packages\SideFXLabs19.5\vex\include

They are. Thanks.
