So you want to find out what licenses are in use? Maybe you want to know licenses that are checked out that might be over 30 days since that user logged in. Maybe you want to know for longer periods of time. You can get this from the Citrix Cloud console. You can also get it another way. And you can filter down to based on if it has been a period of time since the user accessed. This example gets all users then filters down to the latestLogonTime of older than 30 days.

# Script to get license use from Citrix Cloud. Tested with Powershell ISE. Also requires secure-client.csv with ID, Secret, and CustomerID in CSV to pass to Citrix Cloud.
# This creates a csv with the consumerID, deviceCount, consumerDisplayName, latestLogonTime, and firstLogonTime.
<# All fields available:
consumerId          : user@company.com
consumerDisplayName : user
deviceCount         : 0
userId              : user@company.com
upn                 : user@company.com
userName            : user
domain              : domain
latestLogonTime     : UTC Time
firstLogonTime      : UTC Time
