How can I write a script to uninstall Zscaler (pass required) from a Jamf policy?

I am looking at this script as a basis to write my own, perhaps  it will also help you. Lines 15-24 could also be used for  an EA, just my .02, about to go on holiday so may be a few weeks before I start. AHaron-Zscalar -Script 

I've used this successfully:

#!/bin/sh

function removeZscaler () {
PWord=`echo 'password' | base64 --decode`
/bin/sh /Applications/Zscaler/.Uninstaller.sh $PWord
}

#Is Zscaler installed
if [ -f "/Applications/Zscaler/Zscaler.app/Contents/Info.plist" ]; then
removeZscaler
else
echo "Not Installed"
fi

I am sure zscaler has this function. However, this is the kind of thing you want to go to the vendor for. You guys are paying for zscaler support, open a ticket and make them support you.
