How do I use mcpAuthorization to restrict certain tools in a k8s land

[mkchakra]

I want to add a mcpAuthorization to the TrafficPolicy , however it does not have a field called trafficPolicy. The agentGateway site talks about mcpAuthorization.
My use case is
- add a mcp server as a backend, route and traffic policy
- however i want to block some tools based on usernames .

How do i do it in the k8s land ? I looked at the crds could not find the mcpAuthorization field in any crd ?
