I have been trying to implement MutatingAdmissionWebhook with Config Connector resources but to no avail, and therefore wanted to ask if anyone else had implemented this or if it is even possible? To summarise, I am working on having a MutatingAdmissionWebhook deployed that can change an IAM Service Account creation request done via Config Connector, as described here: https://cloud.google.com/config-connector/docs/reference/resource-docs/iam/iamserviceaccount
So far I was able to modify requests for Pods, but whenever I use IAMServiceAccounts in my webhook the request is not being picked up.
