-- List all the messages in a channel. Returns a paginated list of
-- @ChannelMessages@. By default, sorted by creation timestamp in
-- descending order.
--
-- Redacted messages appear in the results as empty, since they are only
-- redacted, not deleted. Deleted messages do not appear in the results.
-- This action always returns the latest version of an edited message.
--
-- Also, the x-amz-chime-bearer request header is mandatory. Use the
-- @AppInstanceUserArn@ of the user that makes the API call as the value in
-- the header.
