Playing multiple animations simultaneously in Vision OS.

It seems that Vision OS doesn't yet support Blend Shapes, so I've created a character with body animations and skeletal animations for the mouth with vowels, all animations are in USDZ format in Reality Composer Pro.

I would like to know if there is any way to play a body animation of the character and simultaneously multiple mouth animations one after the other without stopping the body animation.

When I trigger the mouth animations, the body animation pauses, and when the mouth animations finish, the body animation resumes when I use blendLayerOffset 1 on the mouth animations. However, this is not what I want. I would like the body animation to continue while the mouth animations play simultaneously.

Thank you!
