Apollo Router standard events

Hi folks!

I’m trying to enable standard events for my local Router by adding the following lines to config:

        error: error

but I’m getting the error message during router start up:

{“Not connected to GraphOS. In order to enable these features for a self-hosted instance of Apollo Router, the Router must be connected to a graph in GraphOS (using APOLLO_KEY and APOLLO_GRAPH_REF) that provides a license for the following features:\n\nConfiguration yaml:\n* Advanced telemetry\n .telemetry…events\n\nSee Enterprise Features of the Apollo Router for more information.”

Does it mean that standard events are only available in Cloud or with Enterprise plan? Or am I doing something wrong? There is no mention of paid subscription in the corresponding section of the documentation
