Actually, it does work between clusters. I have to argue with @Radoslaw, But you won't see the full trace - for example it's not possible to see a service flow across different dynatrace environments. But for a particular external service, you can follow the traces to other Dynatrace environment - the other environment UI will open up for you and the context is passed. This even does not need any interconnection of those clusters nor the W3C headers.
Secondly, you get the ability to put data from a remote environment onto your dashboard. For this you need the connection to the cluster (not Cluster ActiveGate in case of managed, but the Cluster address itself). But beware - tokens do not have scope limit - so any environment having the token will have access to all data that can be put on the dashboard.
