Error importing raspi k3s cluster into rancher (Cluster admin)


Im relatively new to rancher and am trying to setup a demo cluster to experiment on. Right know i have the rancher UI installed on a microk8s cluster and am truing to import a k3s cluster running on a raspberry pi os 64bit.

the cluster fails to import with an error in related resources (Error Mgmt Cluster [ c-m-pch2nlpn])
I think the error involves to prerequisite of setting the cluster admin as i dont think im doing that right as i also get at the end of the error “cluster-admin” not found
If that is the case and i think it is how do i go about creating the admin or getting the admin details

any guidance would be appreciated
if you require more detail i will do my best to provide it
