title: Get-AzureADAuditDirectoryLogs Find users who updated there phone number
body: <p>I need to find all users who changed there phone number on AzureAd. I was hoping I could find that information on Get-AzureAdAuditDirectoryLogs but I am not able to find anything. </p>
  
  <pre><code>Get-AzureADAuditDirectoryLogs -All $true -Filter "activityDateTime le 2019-12-18 and Category eq 'UserManagement' and OperationType eq 'Update' and ActivityDisplayName eq 'Update user'" 
  </code></pre>
  
  <p>My question is. Where and how can I find when a users has added or updated a field on there account?</p>
