limit: Optional[int]

The number of messages to retrieve.

before: :class:`Message` or `datetime`

after: :class:`Message` or `datetime`

|
Retrieve messages after this date or message.

If a date is provided it must be a timezone-naive datetime representing UTC time.

|
around: :class:`Message` or `datetime`
|
|
Retrieve messages around this date or message.

even number then this will return at most limit + 1 messages.

reverse: bool
|
|
If set to true, return messages in oldest->newest order. If unspecified,
|
|
this defaults to ``False`` for most cases. However if passing in a
|
|
``after`` parameter then this is set to ``True``. This avoids getting messages
