【 TOGGLES 】
These are the toggles and predetermined expressions. You can put hotkeys to toggle them, I tested it on VSeeFace and it worked. If for you it does not work and possibly is a model's problem, tell me ASAPPPP!
You can do more using unity, Hana tool, Perfect Sync and others. I tried to put it on but my stupid unity novice head couldn't do it.... LOL
