You can optionally whitelist any of these 4 removed values by passing it comma separated to the variable instead of `true`. (ex: `MSG_MINIMAL: event` or `MSG_MINIMAL: ref,actions url`, etc.)

You can get the timestamp of the parent message from the message URL in Slack. (ex: `SLACK_THREAD_TS: 1586130833.000100`)
