Dear community, I am using Houdini 21 Indie purchased via Steam on macOS and would like to install SideFX Labs, but I encountered several issues:

1. The official documentation only provides Windows-specific installation paths, and I could not find updated instructions for macOS.

2. The Steam-installed Houdini Launcher does not start on macOS due to a missing libSYS.dylib, so I cannot use it to install Labs.

3. The Launcher which is downloaded from the office website works, it only installs SideFX Labs to /Applications/Houdini/sidefx_packages/SideFXLabs21.0.json, which does not apply to the Steam version of Houdini.

Online references I found are outdated.

Could anyone kindly provide the detailed manual installation steps for SideFX Labs on macOS with the Steam version? In particular, which directory should I place the Houdini 21 packages folder in?
