Hi, I have a rancher extension which uses a custom node driver and when I create a RKE2 cluster through the Rancher UI I see that the UI makes a call to

/v1/rke-machine-config.cattle.io.tritonconfigs/fleet-default

to create each of the machine pools before creating the cluster at

/v1/provisioning.cattle.io.clusters

and the machine pool creation API calls correctly have the info from the selected cloud credential but then I also notice that the API call to create the RKE2 cluster includes a field called

cloudCredentialSecretName

with the ID (not name) of the cloud credential that was used to populate the machine config. I'm wondering what this field is used for since the data from the cloud credentials was already fetched and used to populate the machine configs... Does this need to be passed to the create cluster API call?
