The secrets are not generated on Raspberry PI cluster

I followed the usage instructions with a few modifications because my K3S is accessible as root user as installed:

$ sudo helm repo add mittwald https://helm.mittwald.de
"mittwald" already exists with the same configuration, skipping

$  sudo helm repo update
Hang tight while we grab the latest from your chart repositories...

$ sudo helm upgrade --kubeconfig /etc/rancher/k3s/k3s.yaml --install kubernetes-secret-generator mittwald/kubernetes-secret-generator
Release "kubernetes-secret-generator" does not exist. Installing it now.

$ sudo kubectl get secret mysecret -o jsonpath='{.data}'
{"username":"UGxlYXNlQWNjZXB0Cg=="}

From above output, it appears the secret only contains the predefined element "username" and that the password is not generated. Further, if I uncomment a couple of lines from mysecret.yaml, it complains:

$ sudo kubectl apply -f mysecret.yaml
error: error validating "mysecret.yaml": error validating data: ValidationError(Secret): unknown field "spec" in io.k8s.api.core.v1.Secret; if you choose to ignore these errors, turn validation off with --validate=false

Then I noticed the pod failing:

$ sudo kubectl get pods -n default
NAME                                          READY   STATUS             RESTARTS      AGE

$ sudo kubectl logs kubernetes-secret-generator-9b7946ff5-znxfz
standard_init_linux.go:228: exec user process caused: exec format error

From what I can see, the underlying image is for x84_64 architecture. Can we have one for ARM64?
