Adding node on Rancher 2.6

Just installed a single node Rancher 2.6
Have no idea how to add additional node.
I seem to be able to download YAML file from existing cluster node, but what do I do with it to add additional nodes to existing cluster?

Same problem with a bare metal cluster running 2.5.8. Where did the option go to copy and paste a docker call to bootstrap new worker nodes? Did I miss something?

I still haven’t found a way to add node to single cluster I have.
what I was able to find out was that you add additional node to “node pool” and create cluster from available “node pool”
so it seem like I need to find a way to add node to node pool then create new cluster using all the nodes in the node pool
