Hello, I'm new to the Hibernate world and havent much info on how to do left joins using QueryOver. I'm trying to convert to following over to QueryOver. Thanks in advance.

select
        CommunicationMaster.CommunicationID as CommunicationID,
       
        Staff.StaffID as StaffID,
       
        CommunicationDetail.Status as Status
       
    from
        dbo.[shr_PC_Communication] CommunicationMaster
    inner join
        dbo.[shr_PC_Communication_Detail] CommunicationDetail
            on CommunicationMaster.CommunicationID=CommunicationDetail.CommunicationID
    left outer join
        dbo.[shr_Staffs] Staff
            on CommunicationDetail.StaffID=Staff.StaffID
      
    
    where
        (
            CommunicationMaster.Created_Date between @p0 and @p1
        )
        and (
            CommunicationMaster.IsRemoved is null
        )
        
        and (
            CommunicationDetail.IsArchived is null
        )
        and (
            CommunicationDetail.Status in (
                @p3
            )
        )
        and (
            Staff.StaffID in (
                @p4
            )
        );
