Get all user attributes for a specific user object (including empty/null values)

Good Morning,

Please could someone tell me how I can get every single user attributes (all 200+ odd) for a specific user object?

Get-ADUser 'me' -Properties * | fl

This command does not produce all attributes - it only seems to show attributes that have values?

Is there a way to get every attribute associated with a user object please?

Thanks very much
