Cannot find pose tracker in Machinima 2022.2.1 Linux

I installed Machinima version is 2022.2.1 Beta.


When I follow the instructions, I can’t find the option “Pose Tracker”
Uploading: MachinimaAnimationMenu.png…
“MAXINE POSE TRACKER” also not found in Extension.

Does the POSE Tracker function have specific package requirements?
