  "policyURI": "ipfs://...", // not dispute-specific
  "attachment": { // dispute-specific

On the Case Details page, display a link to the "extra description" if disputeDetails.attachment is set in the object obtained from the SDK. Use a paperclip 📎 icon.

Warning: attachment.label is optional, its default value should be "attachment".
