I have no idea about the required resources, could you confirm that these are correct?

• A ServiceBus topic in the main ServiceBus: keda-e2e-receive-event-grid-topic
• A ServiceBus topic in the alternative ServiceBus (we use it for podidentity impersonation test): keda-e2e-receive-event-grid-topic
• A new ServiceBus namespace: keda-e2e-servicebus-namespace-event-grid including
  • Azure Service Bus Data Owner role asignment
  • An authorizartion rule
  • A topic keda-e2e-receive-event-grid-topic
• An EventGrid subscription
• An EventGrid topic
