Layout

No action required

This plugin exports a UI tab that you can use as a new Feature Flags tab for a service or for any other layout page. The following configuration is set by default in Layout under Admin for Service and you do not need to change anything:

Also you could add a conditional like isHarnessFeatureFlagAvailable which is met when the harness.io/project-url annotation is present in the software components's catalog-info.yaml definition file.
