Hi,
I think there is some confusion here. The app that you linked to on SplunkBase is one that was created by a community user and not Splunk. It happens to have the word "synthetics" in the name, but that is not related to Splunk Synthetics--which is the synthetic monitoring solution provided by Splunk Observability Cloud. For help with the app you found on SplunkBase, you'll need to contact the developer directly.
