How do I define a tenant's access to a namespace?

[Bennu-Li]

I learned from the doc that A tenant receiver only receives notifications from the namespaces that the tenant has access to. How do I give a tenant permission to access a namespace?

You can follow this to give a tenant permission to access a namespace for a native Kubernetes cluster.

If you used other Kubernetes platforms such as KubeSphere, and Rancher ..., please go to the relevant community for help.
