Describe the bug
Can't send custom webhooks that expect specific payload bodies.
- Seems like we are wrapping all custom webhook payloads in { "Content": ... } which is specific to Chime.
- And also seems like we are requiring a title and constructing the message as "$title\n\n$textDescription" which would break custom JSON payload to custom webhooks.
