Hand toggle

Hello,
I have a problem with a hand toggle.

I wanted to make my character be able to hold an object in his hand when toggled on.
I made the “animation” for the toggle in unity so that the fingers wrap around the object, and it works in unity just fine.
in vrchat the toggle works but only with the object itself. The hand animation doesn’t work, the fingers stay in the default position which makes the fingers go through the prop.

I cant find any useful info about this online and I have absolutely no idea how to fix this.

I watched a tutorial to do this an I did everything just like in the video, I checked everything 3 times and even tried different stuff but i just cant fix it.

I hope someone can help me with this cause im going insane.
