(Swift 3,4,5...) SharePoint -- Approve a File Submitted for Content Approval

    // The more common case is to use SharePoint Online authentication (via the SPOIDCRL cookie).
    // If so, do not set Login, Password, LoginDomain, and NtlmAuth, and instead
    // establish the cookie as shown at SharePoint Online Authentication

    // Only persons who have Full Control or Design permissions can approve or reject
    // items or files in a list or library that requires approval. Other site users
    // can only view what they have permission to view or what they have uploaded
    // themselves.
    // 
    // Important:  Approval or rejection of items or files in lists or libraries must
    // be done one at a time. You cannot approve or reject multiple items or files in
    // one operation.
