cluster wide sensors

[or-adar]

Hi,
let's say I have EventBus, Sensor & EventSource on a certain namespace. let's name it argo-events.
can I define my Sensor CRD in my argo-events ns in a way that it'll create a k8s resource in other namespaces?
For instance, trigger creation of custom CRD or Deployment in ns test (while EventBus, Sensor & EventSource were created in argo-events).
if so, will setting namespace: test for triggers[*].template.k8s.source.resource will do it?

Also,
is it possible to watch k8s resources in other namespaces?
For example, watch for deployment updates in namespace test while having EventBus, Sensor & EventSource on argo-events ns.
is it also configurable in a way that I would be able to retrieve data from the k8s event?
