Additionally, the aws cli can be used to determine which version of the UXP add-on is installed in the cluster

# Assuming cluster-name is my-cluster, below command shows the version of coredns installed. Check if it is same as the version installed via EKS add-on
aws eks describe-addon \
    --cluster-name my-cluster \
    --addon-name upbound_universal-crossplane \
    --query "addon.addonVersion" \
    --output text

# Output
v1.9.1-eksbuild.0
