<a id="attachment"></a>
###  `ATTACHMENT`

Emitted when the incoming message contains an attachment of any type. This event is emitted after the attachment-specific event (`ATTACHMENT_AUDIO`, `ATTACHMENT_FALLBACK`, `ATTACHMENT_FILE`, `ATTACHMENT_IMAGE`, `ATTACHMENT_LOCATION` or `ATTACHMENT_VIDEO`). Thus, the receiving an attachment message causes emitting two events:
1. an attachment-specific event (e.g. `ATTACHMENT_IMAGE`)
2. the `ATTACHMENT` event.
