    // The reason I didn't initialize the List<> fields is because Slack (sometimes) gives errors
    // when it encounters an empty list in the generated JSON.
    // The proper solution if/when you don't want un-initialized fields is to have a Gson type adapter that skips empty lists
    // (e.g. something like https://stackoverflow.com/questions/11942118/how-do-you-get-gson-to-omit-null-or-empty-objects-and-empty-arrays-and-lists)
