Retrieving description of an incident via webhook step in an incident workflow

Based on the Pagerduty documentation, it seems like “description” field is no longer supported and only the “title” can be retrieved via webhook. These two fields are very different, as one is a quick summary and the other provides scope and context necessary to understand an incident. Is there a workaround to retrieve the description field via webhook? This is normally where we would put a paragraph of additional critical context as such as the Slack thread of a user-reported issue, details about the scope of the issue, etc. Does anyone have any advice on what to do?
