    //  In my test case, this is the result (see below)
    //  Apparently, this lists folders without listing subfolders (aka child folders)
    //  There's another REST API call to list child folders.

    //  The output from the above loop:

    //  	Archive
    //  	Deleted Items
    //  	Drafts
