Create a UI element called "Access NiFi" under Site Admin for Acumos Admin to access the back-end NiFi registry.
- The NiFi Registry URL needs to be formatted per a Spring environment variable, e.g. nifi.registry.url
- The URL needs to be launched in such a way that the "Authorization" header with the current Bearer token is included in the request. In testing, launching via a new tab does not appear to include the Authorization header, so some testing of the approach is needed to ensure the header is included.
