How do I see console.log output in the squirrelEvent

Hi,

I have copy and pasted the sample code in to my main.js

```
switch (squirrelEvent) {
case "--squirrel-install":
console.log("install event ========================");
spawn("powershell.exe", [`${appFolder}/../appx/install.ps1`]);
````

How do I see output of the console.log?

I did `SET DEBUG=*`

I run `setup.exe` in the powershell. But there is no output in the terminal.
