What would you like to be added

Support for escalate verb for ClusterRole

Why is this needed

Error: resolving resource: the "clusterroles" resource does not support the "escalate" verb, only [create delete deletecollection get list patch update watch]

Something interesting is if you check this with kubectl auth can-i without the -A flag, it says it is not a known verb.

kubectl auth can-i escalate clusterroles                                                                    

Warning: resource 'clusterroles' is not namespace scoped in group 'rbac.authorization.k8s.io'

Warning: verb 'escalate' is not a known verb

yes

It works with -A

kubectl auth can-i escalate clusterroles -A

yes

I tried this with kubectl-who-can as well kubectl-who-can escalate clusterrole -A still fails.
