Extension attribute for Microsoft Office 2021

I had this extension attribute that will tell me if the mac had Office 2016 or 2019 installed, I need one now for office 2021, can anyone help me modify it?

#!/bin/bash

wordVersion=$(defaults read "/Applications/Microsoft Word.app/Contents/Info.plist" CFBundleShortVersionString)
majorVersion=$(awk -F '.' '{print $1}' <<< "$wordVersion")
minorVersion=$(awk -F '.' '{print $2}' <<< "$wordVersion")

if [[ $majorVersion -ge "15" ]]; then
if [[ "$majorVersion" -ge "16" ]] && [[ "$minorVersion" -ge "17" ]]; then
echo "<result>2019</result>"
else
echo "<result>2016</result>"
fi
else
if [[ -d "/Applications/Microsoft Office 2011/" ]]; then
echo "<result>2011</result>"
else
echo "<result>Not Installed</result>"
fi
fi

exit 0
