Developer checks
I have:

• Run the formatter and made sure there are no IDE errors
• Written tests for the changes (accessibility tests, unit tests for controller, data services, services, view models, etc)
• Manually tested my work with and without JavaScript
• Tested any Views or partials created or changed with [Wave Chrome plugin] -- Issues not related to this code change.
• Updated/added documentation in [Confluence]
• Updated my Jira ticket with information about other parts of the system that were touched as part of the MR and have to be sanity tested to ensure nothing’s broken
• Scanned over my own MR to ensure everything is as expected and it looks right in the browser
