Brand new to ExtendScript Toolkit – please be patient with me.

I am trying to do a simple thing, which is similar to Photoshop’s Action. Since I have tons of files to set Exposure to “-12” then I was hoping there was some simple scripting which would allow me to run it as soon as the file opened. The intention of this script is to circumvent the task of clicking on the Effects menu> Color Correction> Exposure, followed by entering the value -12 and clicking enter.

This is what I have so far, but it obviously does not work, except that it does select the active layer and it does not give me an error for calling applyEffects, so I guess I just need some help on what to add within the applyEffects function or what is to follow

app.activeDocument.activeLayer.applyEffects("Exposure",-12);

Is there some kind of fxExposure function to call and set the exposure to “-12”?

As usual thanks in advance
