How can I query WMI GroupUser objects and select PartComponent attribute

Question

I want to select Account attribute in this query

example : SELECT Description, Disabled, Domain, FullName, Lockout, Name, SID FROM Win32_UserAccount WHERE Domain = '<domainName>'

I'm trying to get

SELECT PartComponent FROM Win32_GroupUser WHERE GroupComponent=`"Win32_Group.Domain='xxx',Name='xxx'`""
