 These will specify whether the thread is a single user chat or a group chat.
 This is required for many of `fbchat`'s functions, since Facebook differetiates between these two internally

+Getting the ID of a group chat is fairly trivial otherwise, since you only need to navigate to `<https://www.facebook.com/messages/>`_,
 click on the group you want to find the ID of, and then read the id from the address bar.
 The URL will look something like this: ``https://www.facebook.com/messages/t/1234567890``, where ``1234567890`` would be the ID of the group.
 An image to illustrate this is shown below:
