Edit the second parameter in Layer Control with JavaScript

I often encounter some png/psd with dirty alpha, so I want to batch process these png/psd.
I use "Autotrace" to get a clean alpha, then set a new mask to the layer with the "set matte" effect, and then save as png/psd
I tried to automate the whole process with a script, but after querying, knowing ae doesn't help me click "OK" in "Autotrace", and I don't know how to set the option in "take matte from layer" in "set matte" to " mask"

due to the Chinese labels, I am not 100% sure what exactly you want to set.

You can set track matte layer and track matte type with AVLayer.setTrackMatte():

Or are you trying to set the parent?
