Could not use Mark Blendshape in Maya

Seems to be a simple question. I have watched the Audio2Face tutorial videos, but things still make me frustrated these days. I just want to use the Mark Blendshape in Maya. When open male_bs_46.usd in Maya, there is nothing but a neutral head and a joint. No blendshapes is available. I am wondering how can I get the Mark template blendshapes used in Audio2Face.

Maya 2020
Audio2Face 2022.1.0-rc.3
