How do I toggle accessorries with three-vrm?

[oz123]

My model has two Shape Keys, which can be closed or open (values 0-1) which I can toggle using blender.
However, I could not find an obvious way to do this using this library. Can you maybe give me a hint?

There is a feature called "BlendShapeProxy (in VRM0.0)" or "Expressions (in VRM1.0)" in VRM, which enables you to control morphs.

If your model has the feature, you should be able to control this using VRMExpressionManager like this:

vrm.expressionManager.setValue("<name of your morph>", <target value in 0-1>);
