Manual Documentation

Have you made any changes that should be documented in manual_readme_content.md? N/A

The following changes require documentation in manual_readme_content.md:

• New, updated, or removed REST handlers
• New, updated, or removed authentication methods, especially complex methods like OAuth
• Compatibility considerations with respect to deployment types (e.g. actions that cannot be run on cloud or an automation broker)

• I have verified that manual documentation has been updated where appropriate
