Howto set a default certificate for the ingress controllers of the managed clusters?

Hi folks,
https://rancher.com/docs/rke/latest/en/config-options/add-ons/ingress-controllers/ describes how to set a default certificate for the ingress controllers of my RKE cluster, but how can I set a default cert for the ICs on the clusters deployed through RKE?

Every insightful comment is highly appreciated

Hi Harri,

Maybe I have the same problem as yours.

This may be helpful, but I have not tried yet.

Thanx for the hint. I just added a metoo to keep this ticket alive.
