    Usage info

    This method returns a list of all reactions for a single item (file, file comment, channel message, group message, or direct message).

    An item will always have a type property, while the other properties depend on the type of item. The possible types are:

    • message: the item will have a message property containing a message object and a channel property containing the channel ID for the message
    • file: this item will have a file property containing a file object
    • file_comment: the item will have a file property containing the file object and a comment property containing the file comment

    The users array in the reactions property will always contain the authenticated user, but might not always contain all users that have reacted. The value of count, however, will always represent the count of all users who made that reaction (i.e. it may be greater than users.length).
