Enable channel disable

I would like to create this function but I certainly make some mistakes because it does not work

I have a channel with the name test

I would like to create a button that enables or disables this function

this is what I have now

Option =activeDocument.channels
try {
    
if (Option.channels["Test"].visible == true) {
Option.channels["Test"].visible = false;
} else {
Option.channels["Test"].visible = true;
}
}
catch (e) {}
app.refresh();
