• (Summarize the changes that have been made to the platform)

Testing done

• New code is covered by unit tests
• Describe what the old behavior was prior to the change
  Swagger docs still showed the old urls without the decision_reviews prefix
• Describe the steps required to verify your changes are working as expected. Exclusively stating 'Specs run' is NOT acceptable as appropriate testing
